See this StackOverflow question and answer. The only way to make progress is to note the problem right here and to work on it at some point rather than just say "this grammar on GitHub is not a very good reflection of it. MATLAB has further exponentiation operators (.^-, .^+, .^~, ^-, ^+, ^~) for example, and there are entire categories of syntax, e.g. all the object-oriented functionality, that are not covered at all."
