test_memsize_of_iseq fails on repeat tests and it seems to difficult
to solve immediately. Now this test is skipped.
It seems that the result of `memsize_of(Object.new)` are increased.
Why...?
Constant definitions are affect on outer namespace of an anonymous
module. To define constants on the anonymous module, this patch
uses Module#class_eval(str).
Rational literals are those integers suffixed with `r`. They tend to
be a part of more complex expressions like `123/456r`, but in theory
they can live alone. When such "bare" rational literals are passed to
case-when branch, we have to take care of them. Fixes [Bug #17854]
Remove discussion of Ruby 2.7 specific handling of keyword
argument separation. Add a small example of keyword to
positional hash conversion for methods not accepting
keyword arguments.

Instead of on read. Once it's in the inline cache we never have to make
one again. We want to eventually put the value into the cache, and the
best opportunity to do that is when you write the value.
This change implements a cache for class variables. Previously there was
no cache for cvars. Cvar access is slow due to needing to travel all the
way up th ancestor tree before returning the cvar value. The deeper the
ancestor tree the slower cvar access will be.
The benefits of the cache are more visible with a higher number of
included modules due to the way Ruby looks up class variables. The
benchmark here includes 26 modules and shows with the cache, this branch
is 6.5x faster when accessing class variables.

Benchmark.ips calling `ActiveRecord::Base.logger` from within a Rails
application. ActiveRecord::Base.logger has 71 ancestors. The more
ancestors a tree has, the more clear the speed increase. IE if Base had
only one ancestor we'd see no improvement. This benchmark is run on a
vanilla Rails application.
Benchmark code:
```ruby
require "benchmark/ips"
require_relative "config/environment"
Benchmark.ips do |x|
x.report "logger" do
ActiveRecord::Base.logger
end
end

To invalidate some callable method entries, we replace the entry in the
class. Most types of method entries are on the method table of the
origin class, but refinement entries without an orig_me are housed in
the method table of the class itself. They are there because refinements
take priority over prepended methods.
By unconditionally inserting a copy of the refinement entry into the
origin class, clearing the method cache created situations where there
are refinement entry duplicates in the lookup chain, leading to infinite
loops and other problems.
Update the replacement logic to use the right class that houses the
method entry. Also, be more selective about cache invalidation when
moving refinement entries for prepend. This avoids calling
clear_method_cache_by_id_in_class() before refinement entries are in the
place it expects.

First, this patch skips `Encoding::Converter.new` for the same encoding.
170531df19/lib/irb.rb (L601)
Next, this is a talk about the condition for skipping. `IRB.conf[:LC_MESSAGES].encoding`
becomes `"UTF-8"` string when `Reline.encoding_system_needs.name` is set in the below.
170531df19/lib/irb/input-method.rb (L269)
OTOH, `message.encoding` is `Encoding::UTF_8`, so these are compared as a string by this patch.
