Countdown@PDC: Day 2 Recap

Sounds interesting. Is there a link yet to the ctp bits of M?
The underlying parsing runtime uses GLR (Generalized LR).
The M grammar compiler produces structured data that drive that runtime.
I always screw-up that reply thing... Should be: @Don Box:
Might have a problem with the name.
Although in lesser use now, 'M' is still an ISO-Standard language: ANSI X11.1-1995 and ISO/IEC 11756:1999
http://en.wikipedia.org/wiki/MUMPS
It is still sold & supported (under various disguises) by Intersystems: http://www.intersystems.com/cache/index.html
It's one of the earliest dynamic type languages, and although a bit clunky by today's standards, still has some features that modern languages struggle to match.
I recall doing a bunch of work in this (and the earlier MUMPS variants) way back when.
