Yes Dan, will do my utmost best to spare some time to do so (and you 
kindly asked
that before, but have so much on my todo stack .. :))
At least I'm very happy that we can run such queries with cwm as pointed 
out in
http://lists.w3.org/Archives/Public/public-cwm-talk/2005JulSep/0001.html

PS slightly related and in realm of fuzzy set, cwm seems to loop with last 
rule
{?X :mu (?C ?M). (1.0 ?M) math:difference ?N} => {?X :mu 
(?C^owl:complementOf ?N)}.
in http://www.agfa.com/w3c/euler/rpo-rules.n3
i.e. it loops for 3rd n3ql query in 
http://www.agfa.com/w3c/euler/example003Q.n3
when running
cwm

- maybe DAWG could write a short note describing the options?  Linked from 
the SPARQL language spec so it's easy to find? 

Yes, I have been thinking about it for a while.

Jos, EricP, did I ever ask you about that?
Are you interested to write a little 2 page
note on querying lists with list:in ?

Anybody else?
