04:40 AM Ruby Bug #15370: Array#=== in long running loop continually consumes more RAM
- Thanks both of you! :-) I saw some bad advice on StackOverflow and new that `case` worked as follows:
case 2
when *[1,2,3]
puts :winner
end
# => winner
So I had assumed it would work. My mistake. -
- I was doing a code challenge and trying to use as few characters as possible (not shown). So instead of using `Array#member?` I tried `Array#===` and it consumed my system's RAM once I switched to that.
The good code here:

- In Ruby 2.3 & 2.4.0 you can do this
~~~ruby
define_method :some_method_name { "asdf" }
~~~
As of my trying 2.4.2 this is no longer supported. Anyone who tries to load my 'read_source' gem will get a failure message in require wi...

- You both have provided better examples as to the differences. Also finding out `yield_self` returns an Enumerator was a new one to me. I guess this feature request can be closed.

- Issue https://bugs.ruby-lang.org/issues/6721 for adding `yield_self` is unnecessary as `BasicObject#instance_eval` will do the exact same thing.
~~~ruby
class BasicObject
alias :yield_self :instance_eval
end
2.yield_self { |x|...

- I found a way to use refinements in a block anywhere! Yay :-)
~~~ruby
module Moo
refine Fixnum do
def to_s
"moo"
end
end
end
class << Class.new # valid Ruby 2.3.0
using Moo
1.to_s
end
# => "moo"

- I would also like the block for `using` to have access to local variables.
~~~ruby
def example(thing)
using MyCapitalize do
thing.my_capitalize
end
end
example "hello"
# => "Hello"
~~~ -
- In Ruby 2.2.3 a refinement could be used in a begin/end block.
~~~ruby
module Moo
refine Fixnum do
def to_s
"moo"
end
end
end
begin # valid Ruby 2.2.3 and NOT Ruby 2.3
using Moo
1.to_s
end
# => "moo... -

I like it. One note: Your code examples don't have a lexically scoped block. For them to work i...
