You can’t. You can only pass generic functions which can have several methods. However, the call `goo(a, 10)` will pick the appropriate method of `goo` (or error if there is none). So you should be ok.

Jeff’s thesis is a good read: [phdthesis/main.pdf at master · JeffBezanson/phdthesis · GitHub](https://github.com/JeffBezanson/phdthesis/blob/master/main.pdf).
