This introduces enum types for range checking/returns, adds a millis(() call
(this returns a uint32_t), and moves over to an auto generated version of the GCS binding
This makes the assumption that the semaphore is available via reference, not pointer
For a singleton object this seems like a reasonable API restriction
This adds nil punning to the generator. It also unifies the emitter for
both singletons and userdata, as they were almost identical to begin
with. This should ease the maintenance burden of adding new types.
