|1)the  built-in method binding.

binging contains the local variable closure.  You can supply it as
the second argument of eval().

  def foo
    a = 25
    b = 55
    return binding
  end

  bind = foo            # returns foo's binding
  p eval("[a,b]", bind) # evaluate as if within foo

|2)the Kernel method  callcc.

It's a continuation.  If you know scheme's call/cc, that's it.  If you
don't know... hmm.. Could somebody explain it please?  Shugo?
