switch self.token {

why would operator += be used as +?

The code looks fine to me. If you think you have found a bug, please provide a test case that fails.

[kayabe]

its not about a bug its about the case in which if use Operator.String() in a AssignmentExpression it removes = for += so it only returns the string of +

[dop251]

Why is it a problem? The fact that the operator sits within an AssignmentExpression provides enough information.

using the parser to turn ast back into code and using Operator.String() as is i would have to do Operator.String() + "=" if operator is not just =
