Given:
#define one(a, b)  a b

What does "one((c,d), {c,d})" expand to?
If {} are considered parentheses, then arm 16.3 would suggest
"(c,d) {c,d}", otherwise I might expect an error because
it is interpreted as one("(c,d)", "{c", "d}").

The "otherwise" is correct; you should get an error.

If this were the company's opinion, I wouldn't be allowed to post it.
