If your subroutines don't do much work, or you're calling them recursively, then the overhead of an AUTOLOAD technique might be prohibitive. Otherwise, I wouldn't worry about it.

I recall Damian Conway's Object Oriented Perl describing a technique to declare subroutines when AUTOLOAD is called, so after the first call there is no AUTOLOAD overhead. If you're concerned enough, you might want to investigate that.

Update: The syntax for this is:

*{$name_of_subroutine_to_create} = \&Name::of::existing::subroutine
