Connor Olding c47136442e don't use coroutines for lexing 
this turned out to be unnecessary,
and some flavors of Lua don't even have coroutines!

Connor Olding 7ccc2b180f rename "defines" to "variables" 
this follows bass' terminology:
constants don't care where they're defined, but can never be changed.
variables must be defined before use, but can be redefined.
defines aren't necessarily numbers.
