(Maybe declare some functions external to ensure their interface is well defined. Maybe generate ASM call stubs.)
- Add an export keyword ensuring that a function is generated even if it is never called. Maybe export can be handled by generating a call that can be used as stub. - Add an export keyword ensuring that a function is generated even if it is never called.

- Add inline ASM
- Syntax asm( "asm...", "asm...", "asm..." ); - aligned with gcc
- Better syntax: asm { asm... } - using real ASM syntax inline!
- Allow inline ASM parameter expansion
- Handle long branches - Handle long branches
- Optimize loops by unrolling them somewhat - Optimize loops by unrolling them somewhat

- Remove unused functions. - Remove unused functions.
- Support calculated pointers eg. *(ptr+i) - Support calculated pointers eg. *(ptr+i)
- Add syntax for encoded chars (eg. PETSCII instead of SCREEN)

- Support ASM syntax check etc.
- Also perform ASM clobber analysis when assigning registers.
- Allow lda <var> or sta <var> to just perform a register copy if possible.
