Yes. If you have merely one type, then simple counting will do, but
with as few as two types, there are many other errors. It is more
than just handy in a large code - I have often had to descend to
binary chop to find where a problem is in C - and remember that it can
be in a macro, so it not easily visible :-(
Actually, there are cases even with a single type of brackets where
it can help. But I agree that it is a minor issue.
