Isn't this a problem in any system that allows function names to be overloaded? Don't you have the same issues if (a) your system has single dispatch and classes that can be extended outside the module in which they're originally defined?

I agree and would say that normally dispatch comes in handy for things like `+`, `length` and of course your own functions where the meaning is the same but the implementation must be different depending on the type.
