TODO TODO

- address more questions/issues from the testability discussions.
Blocked by Commander-x16 v39 release

- get rid of all other TODO's in the code ;-) - get rid of all TODO's and FIXME's in the code
- see if we can remove more ".typeOrElse(DataType.UNDEFINED)" - improve testability further, add more tests
- should we introduce more optionals to get rid of more null pointers? - can we get rid of pieces of asmgen.AssignmentAsmGen by just reusing the AugmentableAssignment ? generated code should not suffer
- see if we can remove more "[InferredType].getOr(DataType.UNDEFINED)"
- use more of Result<> and Either<> to handle errors/ nulls better
- fix the asm-labels problem (github issue #62)
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking) - c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
- optimize several inner loops in gfx2 even further? - optimize several inner loops in gfx2 even further?
- add modes 2 and 3 to gfx2 (lowres 4 color and 16 color)? - add modes 2 and 3 to gfx2 (lowres 4 color and 16 color)?

- a way to optimize if-statement codegen so that "if var & %10000" doesn't use stack & subroutine call, but also that the simple case "if X {...}" remains fast - a way to optimize if-statement codegen so that "if var & %10000" doesn't use stack & subroutine call, but also that the simple case "if X {...}" remains fast
- detect proper variables that are written but never read - mark those as unused too and remove them, such as ``uword unused = memory("unused222", 20)`` - also remove this memory slab allocation - detect variables that are written but never read - mark those as unused too and remove them, such as ``uword unused = memory("unused222", 20)`` - also remove this memory slab allocation
- rewrite expression tree evaluation such that it doesn't use an eval stack but flatten the tree into linear code that uses a fixed number of predetermined value 'variables' - rewrite expression tree evaluation such that it doesn't use an eval stack but flatten the tree into linear code that uses a fixed number of predetermined value 'variables'
