Why should this be taboo?
Provided f is declared as
	sometype * f (void)
it returns a pointer to sometype, and I can subscript that pointer like
any other pointer. After all, in C arrays are treated like pointers to their
first element in almost any context. (Hope, the wording is correct, I don't
want to go through that Arrays-are-not-pointers discussion again)
