rb_env_t may use a flexible array, helps a little even on my busy system:

[ruby-core:65141] [ruby-trunk - Feature #10095] Object#as

I wonder what is the biggest reason that yield may not be the word....
class Fixnum
def yield(*args, &blk)
yield(self, *args)
end
end
puts 1.yield(2, 3) { |one, two, three| one + two + three }
class Array
def yield(*args, &blk)
yield(self, *args)
end
end
[1, 2, 3, 4].select(&:odd?).yield {|x| {total: x.count, data: x}}

Feature #10095: Object#as
https://bugs.ruby-lang.org/issues/10095#change-48994
* Author: Akira Matsuda
* Status: Open
* Priority: Normal
* Assignee:
* Category: core
* Target version: current: 2.2.0
----------------------------------------
We've had so many times of feature requests for a method similar to Object#tap that doesn't return self but returns the given block's execution result (e.g. #7388, #6684, #6721 ).
I'm talking about something like this in Ruby of course:
Object.class_eval { def as() yield(self) end }
IIRC Matz is not against introducing this feature but he didn't like any of the names proposed in the past, such as embed, do, identity, ergo, reference, yield_self, itself, apply, map, tap!, etc.
So, let us propose a new name, Object#as today.
It's named from the aspect of the feature that it gives the receiver a new name "as" a block local variable.
For instance, the code reads so natural and intuitive like this:
(1 + 2 + 3 + 4).as {|x| x ** 2}
=> 100
Array.new.as {|a| a << 1; a << 2}
=> [1, 2]
