TODO
====
- fix multi-decl in for loops, see AstPreprocessor TODO("handle multi-decl movement")
- [on branch: shortcircuit] investigate McCarthy evaluation again? this may also reduce code size perhaps for things like if a>4 or a<2 ....

Other language/syntax features to think about
---------------------------------------------
- underscores in numeric literals for grouping
- chained comparisons `10<x<20` , `x==y==z` (desugars to `10<x and x<20`, `x==y and y==z`) BUT this changes the semantics of what it is right now ! (x==(y==z) 0> x==true)
- postincrdecr as expression, preincrdecr expression (`y = x++`, `y = ++x`) .... is this even possible, expression with side effects like this?
- negative array index to refer to an element from the end of the array. Python `[-1]` or Raku syntax `[\*-1]` , `[\*/2]` .... \*=size of the array
