Hello,

given



It would be pretty cool to be able to select to break on sayHello() or sayHi() independently.

I guess this is not easy to do, since as far as dbg, it's all one line?

dbg has very little to do with such constructs.
You may set breakpoints in respective functions or step through them sequentially. First with F7 you get in the fist function, they by pressing Step-out you leave it and by the next F7 you get into the second one.
