 - DONE: for loops now skip the whole loop if from value already outside the loop range (this is what all other programming languages also do)
 - DONE: asmsub params or return values passed in cpu flags (like carry) now must be declared as booleans (previously ubyte was still accepted).

 - [much work:] add special (u)word array type (or modifier such as @fast? ) that puts the array into memory as 2 separate byte-arrays 1 for LSB 1 for MSB -> allows for word arrays of length 256 and faster indexing
   this is an enormous amout of work, if this type is to be treated equally as existing (u)word , because all expression / lookup / assignment routines need to know about the distinction....
   So maybe only allow the bare essentials? (store, get, bitwise operations?)
