## AST
- Simplify unnecessary `newtypes` with type synonyms
- Data type accessors
- Deal with Strictness/unboxing
- Deal with Location

## Parser
- Secure Names
- Optimize `name` and `whiteSpace`: `take...`, `T.fold`, ...
- Handle escape characters in string literals
- Guard for `on` in `FragmentSpread`
- Tests!
- Handle `[Const]` grammar parameter. Need examples
- Arbitrary precision for number values?
- Handle errors. Perhaps port to `parsers` or use a lexer and
 `regex-applicative`

## Tests

- Golden data within package, `path_graphql` macro.
- Pretty Print golden result
