•Re^10: goto superclass method

Well, then, we're back to my other explanation. You're not calling can("SUPER::bar"). You're calling SUPER::can("bar"), so you're finding yourself. Don't do that. Stop saying SUPER::can. It means practically nothing other than "can", unless you have a "can" method in the current class.

Re^11: goto superclass method by Aristotle (Chancellor) on Dec 23, 2004 at 00:40 UTC
Something must have gotten lost along the way, because the fact that `$self->SUPER::can("bar")` is (usually) the same as `$self->can("bar")` is exactly what I was saying in the very first post… `:-)` (It can only be different if there is a `can` in one of the superclasses though, regardless of whether there is one in the current class.) Basically, I pointed out one of my two mistakes, then explained why it was a mistake, and came up with a broken solution because I missed something I thought I hadn't (that you can ask `UNIVERSALL::can` about `'SUPER::method'`). Then you came along and pointed out my other mistake as well, but said that it somehow invalidated my correct explanation for the mistake I had already spotted. Makeshifts last the longest.	[reply]
