^^^^^^
- 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.
- 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)
- 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
- improve testability further, add more tests
- replace certain uses of inferredType.getOr(DataType.UNDEFINED) by i.getOrElse({ errorhandler })

Perhaps replace all uses of .proc/.pend by .block/.bend will fix that?
(but we lose the optimizing aspect of the assembler where it strips out unused code.
There's not really a dynamic switch possible as all assembly lib code is static and uses one or the other)
- introduce byte-index operator to avoid index multiplications in loops over arrays? see github issue #4
More code optimization ideas
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- 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?
- find a way to let registerArgsViaStackEvaluation not use the stack anymore
- 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
- 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'
- this removes the need for the BinExprSplitter (which is problematic now)
- introduce byte-index operator to avoid index multiplications in loops over arrays? see github issue #4
