Currently, there is not a way to create a sized enumerator in C
with a different set of arguments than provided by Ruby, and
correctly handle keyword arguments. This function allows that.
The need for this is fairly uncommon, but it occurs at least in
Enumerator.produce, which takes arugments from Ruby but calls
rb_enumeratorize_with_size with a different set of arguments.
This fixes instance_exec and similar methods. It also fixes
Enumerator::Yielder#yield, rb_yield_block, and a couple of cases
with Proc#{<<,>>}.
This support requires the addition of rb_yield_values_kw, similar to
rb_yield_values2, for passing the keyword flag.
Unlike earlier attempts at this, this does not modify the rb_block_call_func
type or add a separate function type. The functions of type
rb_block_call_func are called by Ruby with a separate VM frame, and we can
get the keyword flag information from the VM frame flags, so it doesn't need
to be passed as a function argument.
These changes require the following VM functions accept a keyword flag:
* vm_yield_with_cref
* vm_yield
* vm_yield_with_block
When Object#to_enum is passed a block, the block is called to get
a size with the arguments given to to_enum. This calls the block
with the same keyword flag as to_enum is called with.
This requires adding rb_check_funcall_kw and
rb_check_funcall_default_kw to handle keyword flags.
Remove rb_add_empty_keyword, and instead of calling that every
place you need to add empty keyword hashes, run that code in
a single static function in vm_eval.c.
Add 4 defines to include/ruby/ruby.h, these are to be used as
int kw_splat values when calling the various rb_*_kw functions:
RB_NO_KEYWORDS :: Do not pass keywords
RB_PASS_KEYWORDS :: Pass final argument (which should be hash) as keywords
RB_PASS_EMPTY_KEYWORDS :: Add an empty hash to arguments and pass as keywords
RB_PASS_CALLED_KEYWORDS :: Passes same keyword type as current method was
called with (for method delegation)
rb_empty_keyword_given_p needs to stay. It is required if argument
delegation is done but delayed to a later point, which Enumerator
does.
Use RB_PASS_CALLED_KEYWORDS in rb_call_super to correctly
delegate keyword arguments to super method.
This makes objects created via #to_enum and related methods pass
keyword arguments as keywords.
To implement this, add a kw_splat member of struct enumerator and
struct iter_method_arg, and add rb_block_call_kw, which is the
same as rb_block_call_kw with a flag for whether the last argument
is keyword options.
Previously, passing to_enum/enum_for a method that was defined in
Lazy itself returned wrong results:
[1,2,3].to_enum(:map).to_a
# => [1, 2, 3]
[1,2,3].lazy.to_enum(:map).to_a
# => []
I'm not sure why methods that are designed to be lazy do not work
with to_enum/enum_for. However, one possible way to work around
this bug is to have to_enum/enum_for use the implementation found
in Enumerable/Enumerator, which is what this commit does.
While this commit works around the problem, it is a band-aid, not a
real fix. It doesn't handle aliases of Enumerable::Lazy methods,
for instance. A better fix would be appreciated.
Previously, Enumerator::Lazy#with_index was not defined, so it
picked up the default implementation from Enumerator, which was
not lazy.
Based on earlier patch from nobu.
Fixes [Bug #7877]

After 5e86b005c0, I now think ANYARGS is

rb_proc_new / rb_fiber_new, and applies RB_BLOCK_CALL_FUNC_ARGLIST
wherever necessary.
After 5e86b005c0, I now think ANYARGS is

rb_rescue / rb_rescue2, which revealed many arity / type mismatches.
After 5e86b005c0, I now think ANYARGS is

rb_block_call_func_t strict, and apply RB_BLOCK_CALL_FUNC_ARGLIST liberally.
This is my mistake, I thought they were regular objects, but apparently
they are not. We don't need to pin them.

This reverts commit 672ee5f6ed.
* explanation of the class concept, with examples;
* docs for all class methods (most of them just say "Like Enumerable#<methodname>, but chains operation to be lazy-evaluated.", but I believe they are useful this way because now have proper call-sequences and link to corresponding Enumerable's explanations)
* simplified example for ::new to emphasize the main concept
* Enumerable#lazy docs are slightly lightened and linked to this class for more in-depth explanations.

This commit introduces new core class Enumerator::ArithmeticSequence.
Enumerator::ArithmeticSequence is a subclass of Enumerator, and
represents a number generator of an arithmetic sequence.
After this commit, Numeric#step and Range#step without blocks
returned an ArithmeticSequence object instead of an Enumerator.
This class introduces the following incompatibilities:
- You can create a zero-step ArithmeticSequence,
and its size is not ArgumentError, but Infinity.
- You can create a negative-step ArithmeticSequence from a range.

Needlessly exporting can reduce performance locally and increase
binary size.
Increasing the footprint of our C-API larger is also detrimental
to our development as it encourages tighter coupling with our
internals; making it harder for us to preserve compatibility.
If some parts of the core codebase needs access to globals,
internal.h should be used instead of anything in include/ruby/*.

NAN is also float. That of double is called nan(). This is also
