Good question. I've never attempted that when discussing programming
language details, because it hasn't come up, because it would be a
programming error in C to use one in place of the other. And it is
rare to refer to both cases in C.

Rust so far seems to have the same distinction, although I am standing
by to be corrected as necessary, there! :)

At a higher level of abstraction, though, perhaps "grouping" is a good
word.
