Read actually does expand macros. At least for now. In other words, it does the "read characters into memory" and "convert into executable format" phases at the same time.
Calling it expansion time isn't really correct because it doesn't always expand; sometimes it just takes data like 10 or (foo bar) and converts it into the equivalent data structure.

Well, it means you can overwrite them in Arc, possibly to implement defcall or similar, as opposed to in MzArc where they're hidden.
