- rethink the whole "isAugmentable" business. Because the way this is determined, should always also be exactly mirrorred in the AugmentableAssignmentAsmGen or you'll get a crash at code gen time. - rethink the whole "isAugmentable" business.

- simplifyConditionalExpression() should not split expression if it still results in stack-based evaluation - simplifyConditionalExpression() should not split expression if it still results in stack-based evaluation
- remove special code generation for while and util expression
by rewriting while and until expressions into if+jump (just consider them syntactic sugar)
but the result should not produce larger code ofcourse!
- while-expression should now also get the simplifyConditionalExpression() treatment
- fix the asm-labels problem (github issue #62) - fix the asm-labels problem (github issue #62)
- find a way to optimize asm-subroutine param passing where it now sometimes uses the evalstack?
- find a way to let registerArgsViaStackEvaluation not use the stack anymore
- get rid of all TODO's in the code - get rid of all TODO's in the code

- introduce byte-index operator to avoid index multiplications in loops over arrays? see github issue #4

- 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 - find a way to optimize asm-subroutine param passing where it now sometimes uses the evalstack?
