It's a fair cop. Rob should have said "many major languages" or

Yes, there is: the YAZ toolkit has contained a CQL parser since
release 2.0 of February 2003. It's an oversight that the page you
cite doesn't mention this (which I'm sure Ray will fix RSN).

You're right; the core group of SRU implementors have, so far, built
CQL parsers only for the languages that they themselves do the bulk of
their work in.
However, let me put this offer on the table. We at Index Data will
guarantee to deliver a working, tested, standards-compliant,
GPL-licenced CQL parser for any language at a cost of no more than
$10,000 US, probably much less depending on the language. I know
that's not the same thing as the parsers being there today, but I hope
it goes some way to assuaging your concerns. At least it should put
an upper limit on development cost.
