David,
The working group has decided to add a pair of tests based on your example to the SPARQL 1.1 test suite.
test: http://www.w3.org/2009/sparql/docs/tests/data-sparql11/bind/manifest#bind10
query: http://www.w3.org/2009/sparql/docs/tests/data-sparql11/bind/bind10.rq
test: http://www.w3.org/2009/sparql/docs/tests/data-sparql11/bind/manifest#bind11
query: http://www.w3.org/2009/sparql/docs/tests/data-sparql11/bind/bind11.rq
The tests use a nested group graph pattern so as to remove a dependency on GRAPH.
PREFIX : <http://example.org/> SELECT ?s ?v ?z { BIND(4 AS ?z) { # ?z is not in-scope at the time of filter execution. ?s :p ?v . FILTER(?v = ?z) } }
Result:
------------- | s | v | z | ============= -------------
and
PREFIX : <http://example.org/> SELECT ?s ?v ?z { BIND(4 AS ?z) # ?z is in scope at the time of filter execution. ?s :p ?v . FILTER(?v = ?z) }
Result:
--------------- | s | v | z | =============== | :s4 | 4 | 4 | ---------------
