* Change === docs to mention it uses cover?
* Add different example to === docs to showcase
behavior better
* Change include? docs to mention cover?
and clarify the difference
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
Previously, Range#=== treated string ranges that were not endless or
beginless the same as include?, instead of the same as cover?.
I think this was an oversight in 989e07c0f2,
as the commit message did not indicate this behavior was desired.
This also makes some previously dead code no longer dead. Previously,
the conditionals were doing this:
if (RB_TYPE_P(beg, T_STRING)
if (NIL_P(beg)) # can never be true
This restructures it so at the NIL_P(beg) check, beg could possibly
be nil (beginless ranges).
Fixes [Bug #15449]
Range#minmax was previous not implemented, so calling #minmax on
range was actually calling Enumerable#minmax. This is a simple
implementation of #minmax by just calling range_min and range_max.
Fixes [Bug #15867]
Fixes [Bug #15807]
* range.c (range_step): fix the guard condition so that a beginless
range can be turned into a beginless arithmetic sequence.
* test/ruby/test_range.rb (test_step): add assertions for the above
change.

Do not use the optimized version of Range#last when Range#each is
redefined.

This change improves the performance of Range#last method for a range
of integer. This optimization directly computes only required values
only in a range instead of converting all values in the range to an
array. The optimized implementation is 129-16.7k times faster than
the previous one in the benchmark result given below.

Reject ArithmeticSequence in rb_range_values so that methods like
Array#[] raises TypeError for ArithmeticSequence as an index.

* range.c (range_cover): add code for range argument.
If the argument is a Range, check it is or is not
covered by the reciver. If it can be treated as a
sequence, this method treats it that way.
* test/ruby/test_range.rb (class TestRange): add tests
for this feature.

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.

Also, Range#min raises an error if it is endless and a comparison method
is specified.

Now endless range can be created by either a literal `(1..)` or explicit
range creation `Range.new(1, nil)`. [Bug #14845]
This change is intended for "early failure"; for example,
`(1..var).to_a` causes out of memory if `var` is inadvertently nil.

* range.c (range_each): shortcirtuit endless symbol range too, as
well as `#step`.

* range.c (range_each_func): adjust the signature of the callback
function to rb_str_upto_each, and exit the loop if the callback
returned non-zero.
* string.c (rb_str_upto_endless_each): ditto.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63290 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* range.c (range_each): endless range begins with string-like
object should iterate from the converted result string, as well
as `#each` on a string-end range or `#step` method on an endless
range, i.e., `begin.succ` should not be called.

range.c: cast the function type to meet the declaration
This change is for fixing build error on AppVeyor:

string.c
../string.c(4330) : error C4028: formal parameter 2 different from declaration

Typical usages:
```
p ary[1..] # drop the first element; identical to ary[1..-1]
(1..).each {|n|...} # iterate forever from 1; identical to 1.step{...}
```
