I want to dynamically load a module (I call require) and then see if a function exists in that module. I don't mean 'can' via inheritance, but whether a direct call to Module::foo would find anything there.

I tried taking a reference to it in an eval block, but found that it never gives an error. I guess you can take a ref to a non-existing sub and it auto-vivafies or something. I'm afraid looking in the %Module:: hash would do the same thing, wouldn't it?

So how can I tell if the function is implemented in that module, without actually calling it?
