+1

Highlighting the matter with a note (big red box) in the Turtle FPWD 
stating an intention to align Turtle with SPARQL would be good.  Asking 
the community for compelling reasons why not would push the issue along; 
and maybe list the areas of known incompatibility.

If anything comes up, I think we should take the hit, and fix SPARQL 
1.1. (apologies to the chairs of SPARQL-WG!).

What I think is a bad outcome is to address each difference, one-by-one 
in isolation.  A way forward would be for RDF-WG to resolve to align to 
SPARQL unless there are compelling reasons why not.

PS Of the differences,

   (1 2 3 4) .

should probably be removed from SPARQL.
