And that's since the C days btw. The function call is just an operation, 
the callee an operand, so any expression can be there.

Hum, I didn't know that. Why does it make the call slower (other than 
the actual ternary operation), is it because it has to load the function 
address from a register/variable, instead of being a constant value? 
And/or not being able to inline the call?
I mean, the first aspect seems like a very minor impact in performance, 
almost negligible.
