Yes. The names would only be loaded in the namespace that the use with the
compile flag was done. In theory.
If you were really hyper about the namespace stuff, you could probably
write a CGI.pm loader package that wrapped around the use of CGI.pm and
then after loading the methods, it would clear out its own namespace using
a routine similar to Apache::PerlRun's.... But I don't think it would be
worth it.

I always stick to using the OO interface for everything I personally do. I
do feel it does make my code look more consistent since I use objects for
other stuff.

Nice!
