For next release
^^^^^^^^^^^^^^^^
- add compiler error when using boolean with operators <,<=,>,>= (== and != are ok!)
- add compiler error when using boolean on lhs of operators -,*,/,% (+ is ok!)
- add compiler error when using boolean on rhs operators /,%
- add ARRAY_OF_BOOL array type
- test various scenarios of using bool type vs byte actually produces tighter code
make unit test of them?

^^^^^^^^^^^^^^^^^^^^^^^
Compiler:
- bool data type? see below
- add some more optimizations in vmPeepholeOptimizer
- vm Instruction needs to know what the read-registers/memory are, and what the write-register/memory is.
this info is needed for more advanced optimizations and later code generation steps.
