Subject: Procs and Blocks

If I alter the proc class, like so

  class Proc
    def keep(i)
      @i = i
    end

    def whatIGot?()
      @i
    end
  end


and do something like so:

  foo = Proc.new() {|*args|
    ...
  }

  foo.keep(624)

I run into issues when I do something like

def use(*args, &block)
  block[*args]
  $stdout.puts "Block kept:  #{block.whatIGot} :
#{block.whatIGot.class}"
end

use (some, random, arguments, &foo)



here, whatIGot tends to be nil (which is fully understandable, since
we're converting from some proc to a `block' going to a method back to
a proc... but is there any sensable way to keep state?)
