Surely you don't want to reset everything, as that would also reset things like @INC, making your program a little brain-dead. I mean, that's one of the reasons that perldoc -f reset includes the paragraph:
Resetting "A-Z" is not recommended because you'll wipe out + your @ARGV and @INC arrays and your %ENV hash. Resets only pack +age variables--lexical variables are unaffected, but they clea +n themselves up on scope exit anyway, so you'll probably wan +t to use them instead. See "my".

The proper way to go about this is to use proper objects in your program, so that you can have a top level object that is associated with a particular session, and everything else hangs off of that. Then, to reset the session, just generate a new session object.
