Constructors
| UnexpectedEOF !loc !(ContainsSmartQuote loc) | Unexpectedly hit EOF when lexing string |
| BadCharInitialLex !loc !(ContainsSmartQuote loc) | Found invalid character when initially lexing string |
| EscapeBadChar !loc | Found invalid character when parsing an escaped character |
| EscapeUnexpectedEOF !loc | Unexpectedly hit EOF when parsing an escaped character |
| EscapeNumRangeError !loc | Escaped number exceeds range |
| EscapeSmartQuoteError !Char !loc | Found escaped smart unicode chars as `’` or `”` |

data ContainsSmartQuote loc Source #
When initially lexing the string, we want to track if we've seen a smart quote, to show a helpful "you might be accidentally using a smart quote" error.
