Why would "\\t" not double-interpolate to a tab? Also, why would "\\"
not double interpolate to a syntax error?
Given $(...), you might as well give up on correctness and security. It
seems like you really just want to have a limited version of eval called
interpolate, e.g.:
$z = interpolate interpolate $y;
Then you have ultimate control. Of course, you have to check $@ (er, $!)
just like you do with eval.
