Overview
relies on #264
Allows use of macros as macro args.
This only partially enables this feature as it does not support providing arguments to the macros given as args. I didn't implement this because I believe it would require modification to the parser/lexer, and I don't know rust or this repo well enough to try that. It does at least restore the original functionality from Aztec's version though.
To make this work with bubbled args, I had to modify the resolution order for
MacroArg::Ident, as it seemed to be causing a deadlock with the constants mutex. I'm too much of a rust noob to figure that one out, but the change I made seems to have fixed it, maybe because the rust compiler sees that the reference is dropped, or maybe it's a completely different issue unrelated to the mutex.
