For the record, there is another difference which is the SPARQL form:

{ ( "abc" ?x "def" ) . }

and the list must be non-empty -- { () } is not allowed

This is obscure, and takes a few moments to work out what it matches 
(hint: not lists of length 3).

IMO: The best choice here is change SPARQL.  It's not exactly a feature 
for anything other than corner case syntax test cases.
