Good point : there's no parser inside the lexer, like PHP ;-)

In today’s world it seems like this article should be a repo up on github. I had never really thought of github in terms of it’s archiving and historical preservation propertie. FTP if it hasn’t already is going the way of telnet, gopher and Usenet

I guess the "lexer hack" probably has something to do with the lexer refering back to the symbol table to disambiguate things like typecast and function calls? Ie T(x) and f(x). Certainly there are other ambiguities that this particular hack may not resolve?

I worked with Jim at Netscape, and we overlapped at Google later too.

Fantastic, broadly, and intensely talented person.

Hey I worked with Jim!

Fun story: a project we worked on together involved some Python and he suggested that he didn't really know Python. At some point I somehow noticed that he wrote the Python profiler (see the name at the top https://github.com/python/cpython/blob/2.7/Lib/profile.py ). When I asked him about it he made some comment about how he didn't really know the language but he needed a profiler at some point, the language didn't have one, so he just wrote it.

For another cool .y (YACC) and .l (Flex) setup, check out what Postgres uses to parse SQL queries:

I wouldn't count on github for those purposes. They are files hosted under unique accounts -- those accounts could just delete their repos. If there is a need to archive something, I always make my own archive as opposed to bookmarking a hosting site.
