I'm being slightly facetious.

But I have said why, you even responded to it, here, look:

By interface, I mean "contract"; the interface that the programmer uses.
Adding an AUTOLOAD does not change what methods an external programmer ought
to be calling if he's honouring the contract; only changing the documentation
does that. If your user is not honouring the contract, that, rather than
AUTOLOAD, is the problem.

This, of course, is untrue.

have to trade them in on a new model. - D J Trindle, in the monastery
