diff sema/DType.d @ 72:628cb46ab13b new_gen
First update on the way to Arrays! :)
Lexer and ast/Exp now have the types needed.
All that needs to be updated now is the Parser. I suggest two options:
1) Making the Id a class that we can make a ArrayId and PointerId for at some point.
2) Use a struct as now, but adding some bools / ints to give a more abstract description of the type
2) is messy and 1) is slower... :/
