Node has not been managed by GC from Ruby 2.5.
Therefore these codes are not needed. If ObjectSpace depends on Node,
it needs to update the file when node type is updated. Delete node
related codes to avoid such update.
Add a special treatment for when the argument of self is an
integral multiple of 45 degrees.
1i ** (10 ** 100) #=> 1+0i
1i ** (10 ** 100 + 1) #=> 0+1i
(1+1i) ** (10 ** 100) # warning: in a**b, b may be too big
#=> (Infinity+0.0i)
(1+1i) ** (10 ** 100 + 1) # warning: in a**b, b may be too big
#=> (Infinity+Infinity*i)

Previously, we only supported error messages that were constant
strings. This works for the most part, but there are some times
where we want to include some part of the source in the error
message to make it better.
For example, instead of "Token is reserved" it's better to write
"_1 is reserved".
To do this, we now support allocating error messages at runtime
that are built around format strings.

I propose introducing the capability to set the IRB completion kinds via an environment variable, specifically `IRB_COMPLETOR=type`.
This feature aims to enhance the Rails console experience by allowing Rails users to specify their preferred completion more conveniently.
Currently, when using the Rails console, there's no straightforward way to globally set the type completion across a Rails application repository.
It's possible to configure this setting by placing a `.irbrc` file at the project root. However, using a .irbrc file is not ideal as it allows for broad configurations and can potentially affect the production environment.
My suggestion focuses on allowing users to set the completion to 'type' in a minimal.
This enhancement would be particularly beneficial for teams writing RBS in their Rails applications.
This type completer, integrated with RBS, would enhance completion accuracy, improving the Rails console experience.

When transitioning generic instance variable objects to too complex, we
set the shape first before performing inserting the new gen_ivtbl. The
st_insert for the new gen_ivtbl could allocate and cause a GC. If that
happens, then it will crash because the object will have a too complex
shape but not yet be backed by a st_table.
This commit changes the order so that the insert happens first before
the new shape is set.
The following script reproduces the issue:
```
o = []
o.instance_variable_set(:@a, 1)
i = 0
o = Object.new
while RubyVM::Shape.shapes_available > 0
o.instance_variable_set(:"@i#{i}", 1)
i += 1
end
ary = 1_000.times.map { [] }
GC.stress = true
ary.each do |o|
o.instance_variable_set(:@a, 1)
o.instance_variable_set(:@b, 1)
end
```
* Provide a new API compile_file_prism which mirrors compile_file
but uses prism to parse/compile.
* Provide the ability to run test-all with RUBY_ISEQ_DUMP_DEBUG set
to "prism". If it is, we'll use the new compile_file_prism API to
load iseqs during the test run.
This PR implements the once node on interpolated regexes.
There is a bug in Prism where the interpolated regex with the once flag
only works when there is not a local variable so the test uses a "1".
We'll need to fix that.
`String#+@` is 2-3 times faster than `String#dup` because it can
directly go through `rb_str_dup` instead of using the generic
much slower `rb_obj_dup`.
This fact led to the existance of the ugly `Performance/UnfreezeString`
rubocop performance rule that encourage users to rewrite the much
more readable and convenient `"foo".dup` into the ugly `(+"foo")`.
Let's make that rubocop rule useless.
