Fair point. I still fear this feature would cause more confusion than
convenience, particularly because function overloading rules are already so
complex. As an example, changing the type of one element in a tuple becomes a
surprising maintenance liability.

In brief, I think we shouldn't change the language such that writing f(x) may
or may not expand automatically and depending on certain conditions into f(x1,
x2, ..., xn). I actually very strongly believe it would be a net liability.

I'll let Walter decide on this.
