Subject: recontextualizing a block (looking for deep magic)

What I'm trying to do probably isn't possible, but maybe someone knows some 
deep magic.

I'd like something like:

  def runit &b
    a = 42
    pnew = Proc.new &b, binding
    pnew.call
  end

  runit { puts "a is: #{a}" }

  #would print:
  a is: 42

Or course, Proc.new currently doesn't take a Binding object second argument. 
What I'm wondering is if there is any way to 'rebind' or 'recontextualize' a 
block?
