They were initially made frozen to avoid false positives for cases such
as:
str = str.dup if str.frozen?
But this may cause bugs and is generally confusing for users.
[Feature #20205]
Co-authored-by: Jean Boussier <byroot@ruby-lang.org>
This test randomly fails due to the bug reported in [Bug #20314], where
the two timeouts are too close so that they can expire at the same time.
As a workaround, this change increases the time difference between
timeouts. This will reduce the probability of simultaneous expirations
and lower flakiness.

* Implement the redo command
* Commented out a test that does not pass
* Changed key assignment for redo from "\C-[" to "\C-g"
* Changed redo key assignment from `\C-g` to `\M-\C-_`
* Revert the first implemantation
* Implemented redo by sharing `@past_lines` between undo and redo
* Fixed the index of past_lines that is updated when the cursor is moved
* Fixed deletion of the redo history in regular input
* Renamed variables: past_lines -> input_lines
* Rename @position to @input_lines_position
* Deleted unused variables: `@old_byte_pointer` and `@old_line_index`

Since `IO.new` accepts one or two positional arguments except for the
optional hash argument, exclude the optional hash argument from the
check for delegation to `IO.new`.
In some cases Prism was either not raising an appropriate `void value
expression` error, or raising that error when the syntax is considered
valid.
To fix this Prism needs to check whether we have other clauses on the
`begin` rather than just returning `cast->statements`.
* If the `cast->statements` are null and the `cast->ensure_clause` is
not null, set the code to `cast->ensure_clause`
* else
* If there is a `cast->rescue_clause`
* Check if `cast->statements` are null and `cast->rescue_clause->statements`
are null, and return `NULL`
* Check if there is an `else_clause`, and set the node to
`cast->else_clause`.
* Otherwise return `cast->statements` as the node
* return `cast->statements` as the node
See tests for test cases. Note I took these directly from CRuby so if
desired I can delete them since the test will now pass. This only fixes
one test in the `test_parse` file, taking failures from 14 to 13.
This fixes `TestParse#test_void_value_in_rhs` and is related to
issue #2791.

This eliminates the subnode on RationalNode and replaces it with two
integer fields, which represent the ratio for the rational. It also
reduces those two integers if they both fit into 32 bits.
Importantly, this PR does not implement bignum reduction. That's something
I'd like to consider for the future, but it's simple enough for now to
leave them unreduced, which makes it more useful than it used to be.

If the method being called does not have a positional splat
parameter, there is no point in allocating the array, as
decrementing given_argc is sufficient to ensure the empty keyword
hash is not considered an argument, assuming that we are calling
a method/lambda and not a regular proc.
If the method being called does not have a keyword splat parameter,
there is no point in allocating the hash, because the hash will
be unused (as empty keyword hashes are ignored).
This tests ruby2_keywords flagged methods, as well as passing
ruby2_keywords flagged hashes to other methods.
Some of the behavior here is questionable, such as allocating
different numbers of objects depending on whether a block is
passed or whether YJIT is enabled. I think there are likely ways
to eliminate allocations in certain cases. However, this gives
us a baseline and shows us where it is possible to make
improvements.
