Perhaps I've missed something in this thread, but I don't recall anyone
suggesting using the '.' notation in the function declaration, only in
calls (using a syntax similar to the existing syntax for designators in
compound literals and initializer lists).
It looks like you're making a distinction between parameters that can be
named and parameters that can't. That doesn't strike me as useful.
Assuming the language supports named parameters in calls, how is it
useful to allow the author of a function declaration to forbid the use
of named notation for some parameters?
