It isn't just the comments. Suppose you have the value in source code:
0x100
and then in the json code, it's
256u
This kind of thing is way beyond what json is intended for. json is there to extract semantic content, not syntactic.

It's also an excellent way to prove the value of the nascent lexer & parser being written in D.

I think Dil would be a good starting point. It claims 99% of lexer/parser done. https://github.com/azizk/dil |

I have a small (woefully incomplete) list in my Pegged parser generator project README: Parser generators: * Hisayuki Mima's [CTPG](https://github.com/youkei/ctpg), very similar, also done in D. Have a look! * Nick Sabalausky's [Goldie](http://www.dsource.org/projects/goldie). Parsers: * Benjamin Shropshire's [dparser](http://dsource.org/projects/scrapple/browser/trunk/dparser). * Martin Nowak put these gists on the D newsgroup: - https://gist.github.com/1255439 - lexer generator - https://gist.github.com/1262321 - complete and fast D lexer I should also add the parser from Dil and the one from SDC (At least, I suppose there is one in SDC) Jacob, do you have a link to your parser? Also, Timon seems to have a parser, and JM Davis was working on a D lexer. |

If it is going public, can we use a naming convention that make sense for tokens types ?
