Where is this mythical TT3? tt2.org/download/v3/ is still dated June
2001, and tt2.org/download/devel/ is 2.08c. When will the Template3
module be in CVS? *nudge* *nudge*

Ah, nice.

How would this work? I would like to see layered grammars, where you
can have a specialized grammar that conditionally overrides pieces of
a more general grammar (or grammars).

What would DO do? There used to be an item in the TODO list about DO,
but it went away; when I implemented the DO referenced in September, it
was missing from the TODO.
