Subject: Re: ruby1.9 block scope


I hope I'm not belaboring the point, but --

a = Class.new {
  define_method(:f) {
    x
  }

  define_method(:x) {
    33
  }
}.new

x = 44

b = Class.new {
  define_method(:f) {
    x
  }

  define_method(:x) {
    55
  }
}.new

p a.f # => 33
p b.f # => 44

You want a.f == 44.  I do not.

If you think this is a contrived example then you haven't been exposed
to the elegant solution this gives for certain cases.  At run-time we
are creating additional layers of abstraction which translate the
current context into pieces which are passed to lower levels.
