Re^7: Function name in a variable, can't recall the concept (introspection with ->can )

Actually I don't understand the discussion anymore, if the OP was willing to inspect a class the natural solution would be ->can.

If he wasn't inspecting a class ->can would do the job, too.

Are there pathological cases where an approach might break?

Of course, this is Perl, with high flexibility to bend internals.

No, that's not true. If they're trying to resolve a method, then `->can` is correct. If they're trying to resolve a sub, then `->can` can fail The OP is looking for a sub.	[reply] [d/l] [select]
