I agree the second and third are more opaque than your snippets, but that's because there's no function that hides the guts - you could define a Foo::_callables() and then it wouldn't look any more intimidating than your examples (of course that's 90% of what you do, anyway).

But really, if I need to call a series of functions, I'd put them in a hash or array. And I really think the UNIVERSAL::can example is the simplest solution for that case.

Which, silly me, can of course be written

Foo->$bar($baz) if Foo->can($bar);

and then I think there's really no debate anymore over whether that's simple.

Makeshifts last the longest.
