ParseExpectation
ParseState	`ParseState<S, T>` reads value from the stream `S` and build an AST of type `T`. Error strategy: Even in case of success, we keep error information in case we fail later. Think about parsing "abaa" with `"ab"* "c"`, it will directly fails on `"c"`, so it is better to report an error such as `expected "ab" but got "aa"` since the input partially matches "ab"`.
