In Francesco's experience, m[i][j] can be relatively expensive, since
m[i] must return an indexable object. So it's an optimization concern.

Alas, but something like LuaMacro will struggle to detect and handle
EXPR[i,j] since it either would need a lot of history or a lot of
lookahead - in other words, it would need to be a Lua parser.
