Memory sayeth that it's a bug, but one that can't be fixed because it
would cause Much Breakage in the substantial amount of deployed code that
already works around said bug in various ways.
However I haven't had time to read p5p in a while now, so many of those
neurons have been recycled. I have a project that should unrecycle most of
them, but alas no time to do it in yet.
