I would prefer to include the "new" builtin and have that available in 
both BLD and PRD.

My primary motivation is that a substantial number of "in the wild" RDF 
rule sets do something like this to construct new bNodes. For the 
observed usages then the proposed "new" builtin would be sufficient and 
would be implementable in both a BLD and PRD setting.

However, PRD seems to be opting for the "new" action, rather than the 
builtin/skolem function, and that seems to have a Gensym semantics. 
That's clearly a problem. I assume PRD doesn't want two different forms 
of "new" and the true Gensym form can't be in Core.  I'd like to at 
least understand the PRD position here before agreeing to this proposal.
