Suggestion in Parser in module Parse: Use newtype instead of data ▫︎ Found: "data Parser a\n = Parser {runParser :: Position\n -> String -> Either String (a, String, Position)}" ▫︎ Perhaps: "newtype Parser a\n = Parser {runParser :: Position\n -> String -> Either String (a, String, Position)}" ▫︎ Note: decreases laziness

Warning in parseElem in module Parse: Use const ▫︎ Found: "\\ x _ -> x" ▫︎ Perhaps: "const"

Suggestion in parseListElem in module Parse: Redundant bracket ▫︎ Found: "case (parseOthers parser pos' s') of\n Left err -> Left err\n Right (res', s'', pos'') -> Right (res : res', s'', pos'')" ▫︎ Perhaps: "case parseOthers parser pos' s' of\n Left err -> Left err\n Right (res', s'', pos'') -> Right (res : res', s'', pos'')"

Suggestion in parseListElem in module Parse: Redundant bracket ▫︎ Found: "case (parseOthers parser pos'' s'') of\n Left err -> Left err\n Right (res', s''', pos''') -> Right (res : res', s''', pos''')" ▫︎ Perhaps: "case parseOthers parser pos'' s'' of\n Left err -> Left err\n Right (res', s''', pos''') -> Right (res : res', s''', pos''')"

Suggestion in parseDefineFn in module Parse: Redundant bracket ▫︎ Found: "parseCmpString \"fn\" *> (Parser defineFn)" ▫︎ Perhaps: "parseCmpString \"fn\" *> Parser defineFn"

Suggestion in parseCond in module Parse: Redundant bracket ▫︎ Found: "((AST.Cond res res' Nothing), s'', pos'')" ▫︎ Perhaps: "(AST.Cond res res' Nothing, s'', pos'')"

Suggestion in parseCond in module Parse: Redundant bracket ▫︎ Found: "((AST.Cond res res' (Just res'')), s''', pos''')" ▫︎ Perhaps: "(AST.Cond res res' (Just res''), s''', pos''')"
