Due to the change I made previously for how methods are accessed, if you try ot
access one that doesn't exist (For example mistype it or whatever), you get an
internal Lua error about a loop in table get, as opposed to the right error
message about the field not existing.

That's because I had set the class' metatable __index metamethod to point to
the class table, which of course has the metatable with the __index metamethod,
causing a lookup loop.  Blech.
