You could just do a

while(<>){
  eval( 'print "'.$_.'";' );
}

But that leaves horrible security holes open. Horrible, I say. At home, I have some code that parses text, and tries to interpolate variables, but it was really awful to write. I guess you won't need my code as someone else will give a decent solution shortly.
