Quote "Colm does not yet have any documentation".

Then I would hazard that it is not yet a language as without documentation it has no "grammar". At best it is a patois.

TXL, its apparently predecessor, is very well documented (http://www.txl.ca/). TXL is a very interesting approach to parsing and worth reading up on if you're interested in the area (or are waiting for documentation for Colm :)

There seems to be a PhD thesis behind, so you should check it for the grammar.
