Re: sparql list constructor

Jérôme Mainka:

Thanks for trying cwm's sparql support! I'm trying to reduce the  
number of bugs, so any feedback is appreciated.

We do not support that ability at this time. Patches are always  
welcome, but it was decided that supporting the creation of lists  
that way was too difficult for cwm to do, and my time was spent  
elsewhere.
