How can I use CONSTRUCT with Prepared Statements?

Assume a given query which uses pragma output:format '_JAVA_' with CONSTRUCT:
SPARQL DEFINE output:format '_JAVA_'
   CONSTRUCT { ?s ?p ?o }
WHERE
  { 
    ?s ?p ?o . 
    FILTER (?s = iri(?::0)) 
  }
LIMIT 1

In order to work correctly, the query should be modified to:


SPARQL DEFINE output:format '_JAVA_'
   CONSTRUCT { `iri(?::0)` ?p ?o }
WHERE
  { 
    `iri(?::0)` ?p ?o 
  }
LIMIT 1

Equivalent variant of the query is also:


SPARQL DEFINE output:format '_JAVA_'
  CONSTRUCT { ?s ?p ?o }
WHERE
  { 
    ?s ?p ?o . 
    FILTER (?s = iri(?::0)) 
  }
LIMIT 1
