Seconded. Emphatically.
Creating variables in your main namespace is Just A Bad Idea.
Here's a couple of really obvious reasons not to do it:
http:[EMAIL PROTECTED]/msg22156.html
and you almost always want to 'use strict'. There's no
excuse for not using it except laziness (okay, except for
the perl golf crowd, but none of them would ever write
production code without it). And it's false laziness at
that, because it's going to cause you more trouble in the
long run.
Here's a nice post by ovid on perlmonks about strict:

Honestly, using a hash is the best thing.
If you really really really want to import your parameters,
then look at the 'import_names' method in CGI.pm.
Also you should be using taint mode as well. Look at
perldoc perlsec, or
