No. The argument to use must be a bareword.

I don't think so -- they are pulled into the same namespace, so it'll
use the main program's shebang. If you put a shebang, I'd expect it to
ignore it as a comment.

Not necessarily. On the one hand, you could require a .pm, while a use
statement pretty much requires .pm, doesn't it?
Also, modules tend to expect their own namespace.
require'd files are just parsed like an eval(), so though they *can*
switch namespaces, they often don't.
Somebody give me a reality check on that one?
