In languages that allow abstraction over generic types you can also reuse a lot of infrastructure to write parsers. For instance you can parse a string by chaining a bunch of char parsers: string :: String -> Parser String string s = mapM char s On the other hand this probably degrades from c-like performance to python levels so some higher level builtins that are easy to optimize and compile into efficient assembly might be a better idea.
