First, there is no way to effectively pass compiled code between
processes at this time. It isn't likely to happen with Perl 5 because
attempts at loading compiled bytecode from disk have usually had poor
performance and other issues.
Second, what you're proposing is probably not a good idea unless this is
for a small in-house project.

What if the same user has multiple browser windows open and starts on a
new form before finishing the existing form? Remember, sessions are
global to all browser windows.
The right thing to do here is pass the form data the old-hasioned way,
in URLs or form fields. Those are distinct for each browser window.

But why go to all that trouble, generating subroutines on the fly? It
just doesn't seem necessary for processing form input.
