Arg! You beat me to it, since I can't tell heads nor tails of RegExps
;-)

But anyway, wouldn't your solution only handle single argument
functions? 

*runs off, steals Ralph's code, adds 2 asterisk and chucks it in Kernel
instead*

<CODE>
module Kernel
  def call_myself( *a )
    caller[-2] =~/(\w*)'/
    send( $1, *a )
  end
end

def fact(n)
  if n == 0
    1
  else
    n * call_myself(n-1)
  end
end

puts fact(5)
</CODE>

.... now if only I understood your 2 liner regexp black magic ;-)
