While it's anciently stupid that that trick needs to be learned by every programmer instead of having something straightforward readily available, I can't become a fan of this direction when it introduces lowercase macros that might clash with something existing or something that other people will want to write. And yes, I know, we can't do any better in C, due to array decay.
