perlfunc scalar
perlref near end of "Using References" just before "Symbolic references"
"remove_me" => '' would be the simple way. You're getting the eval
result back and have to drop it.
PS: Don't CC me - just respond to list (I get 3 copies when you do).
I CC you because you're the poster and want to make sure you get a
response when AS is slow/down.
