> 
> Fix a few items broken during review of scanner + parser:
> * Make the scanner retain stale newline state on a rewind (as otherwise it must be able to correctly rewind that too, though it doesn't need it). (Probably should revisit).
> * Change StashCode in the builder skip to the zero case, as it crashes for some reason (added TODO).
> 
> Also fix:
> * Drop test based on constant expression evaluation in main parser
> * Support constant defined based on existing constant.
> * Type constants as signed.
> * Added a check that all used functions are defined eventually.
> * Zone allocate strings for simplicity (TODOs to refactor better).
