Function main:Int()
	Local item:= New Item
	
	For item.index = 0 Until 10
		Print item.index
	Next
End

Class Item
	Field index:Int
End

This produces an error:

ATTENTION: Compilation error reported by Trans: Syntax error - expecting '='.

Looks like a bug to me. I usually don't change an object's field with counters, nevertheless it seems like a bug.

Possibly this is intended (note the similar issue if you use a step value it can only be set at the start of iteration). I'm not even certain if all target languages would support this. From a pure programming point of view it seems okay, but an old-style programmer would throw his hands up in horror at the thought of putting a loop counter on the heap.

Yeah it's an odd occasion to write code using the counter like this. It did however confuse me with the error message. Perhaps a clearer error message if this behaviour is not wanted?
