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.

If you want to start with a fresh slate, it's easy. Assuming you haven't changed the current directory or clobbered @ARGV,
exec $^X, $0, @ARGV
Note: That won't pass to the new interpreter options that were passed to the first (like -p), but I bet that's not an issue for you.
Update: Added note.
