I have been wondering if "x" could be an expression that has an operator
that binds weaker than the assignment '='. That may necessitate the LHS
of the assignment to be somehow marked as bound the tightest, i.e.
#define REALLOC_ARRAY(x, alloc) (x) = xrealloc((x), (alloc) * sizeof(*(x)))
Or am I being overly silly?
ALLOC_GROW did well without that. I can't think of a good use case for
a complex expression on the right-hand side. That said, I think I still
have a spare matching pair of parentheses lying around here somewhere,
so let's play it safe and use them. :)
The added underscore is a good idea as well.
