Assignment operators: += -= *= /= %=

These are all statements.

this looks better:

i = i + x;

than:

i += x;

but having fat operators mean people can do:

i += (x -= (y *=  z))----------------;

No, in this language assignment can't be expressions, so you cant put these assignments in an expression.

I guess assignments can be expressions now since I'm using Text.Parsec.Expr to parse everything.
