Eh? That's not what "continue" does in C. Perl's equivalent of C's
"continue" statement is "next". You seem to be asking about a noop
statement.
You have three options:
- Just leave off the else
- Use ;
- Don't put any statements in the block
These are the same options that you have in C. Personally, I choose the
first.

What's wrong with this? It seems fine to me.
