It doesn't really address the question of how you know which one to
use at any particular line of code; or even more to the point, what
mechanism will warn you if you use the wrong one.

My gut feeling about this is that we could probably enforce such a
distinction if we were using C++, but while coding in C I have no
confidence in it.  (And no, that's not a vote to move to C++ ...)
