I can't find anything in the LRM specifying the ordering of multiple assignments (I \
even checked online this time!), so I don't think you can have too many expectations \
about what that snippet does.  FWIW LuaJIT also sets a to 1.

Perhaps there should be a note in the LRM or PiL saying that the order is undefined?

Cheers,
Geoff
