Hi,

If we are worried about the size of the transition table and keeping it
in cache (see remarks from Tom upthread) then adding more keywords seems
a bad idea, as it will surely expand the table. OTOH, I'd hate to make
that a design criterion.
Yeah, me too. Especially because it's an implementation issue against
ease of use. (Or can somebody convince me that functions would provide a
simple interface?)
My main worry has been that the grammar would
be stable.
You mean stability of the grammar for the new additions or for all the
grammar? Why are you worried about that?
Just to quantify all this, I did a quick check on the grammar using
bison -v - we appear to have 473 terminal symbols, and 420 non-terminal
sybols in 1749 rules, generating 3142 states. The biggest tables
generated are yytable and yycheck, each about 90kb on my machine.
That already sounds somewhat better that Tom's 300 kb. And considering
that these caches most probably grow faster than our grammar...

Markus
