type P a = StateT ParseState (Either ParseError) a

data ParseError
Constructors
| UnexpectedToken Token | An error from the parser. Token found where it should not be. Note: tokens contain their own source span. |
| UnexpectedChar Char SrcLocation | An error from the lexer. Character found where it should not be. |
| StrError String | A generic error containing a string message. No source location. |
