I would not use an AUTOLOAD for this. I would follow the strategy of typeglobbing closures that I give at Re: More then one AUTOLOAD in a class hierarchy.
. For one discussion of how AUTOLOAD and OO don't always play ball together see Why breaking can() is acceptable
. The hope that I had of making them play that I discuss there didn't work out, see Detecting function vs method in an AUTOLOAD?
for why not. (Without solving that problem I'm not
going to release a module on CPAN that creates a UNIVERSAL::AUTOLOAD! But hey, I just realized that I could install the AUTOLOAD elsewhere...hmmm...)
UPDATE: That realization is now Class::AutoloadCAN.
