Subject: Restoring global variables?

Hi,

do I have any possibiliy to save and restore global
and instance variables? I think of something like:

  user@host$ cat l.rb 
  class C ; @@i = 0 ; end
  $g = ""

  cache_globals { load 'm.rb' }
  assert $g == "" and C.instance_eval { @@i.zero? }

  user@host$ cat m.rb 
  C.instance_eval { @@i += 99 }
  $g << "foo"
  user@host$

There are several workarounds, for example starting another
process. What is the smartest way to do it?

Thanks in advance.

Bertram
