I do, however, question why #... and #(...) and also ...[i] and
(...)[i] necessarily must have the same meaning given that f(...) and
f((...)) have different meanings.
Yes, it's been a pet bugaboo for me. Even if for realistic numbers of
arguments the quadratic complexity doesn't bite one, I feel dirty
writing such code knowing it's there and on the other hand knowing
that the linear algorithms carry extra cost is again annoying because
it means that in the realistic case, they actually are less efficient
(though not by much).
I should probably just get over it (one way or the other).
