At least the first mention of "b" would not refer to the
second parameter, but maybe to a "b" introduced in the
surrounding scope somewhere.

C++ is offering this as a short-hand, but I'm not seeing
a tidal move in this direction. Being able to refer to
the name of a template parameter (e.g. for constraints)
is useful in a lot of situations. Also, I haven't
seen much use of "auto" parameters in recent library
proposals accepted into C++.
