Safely injecting values into a SPARQL query string

[namedgraph]

Isn't there really an equivalent of ParameterizedSparqlString in RDFLIb? A method to safely inject a variable binding into a SPARQL query string?

I'm not talking about query(initBindings=) here -- I need to produce a new SPARQL string from existing one. They will be executed remotely.

prepareQuery and query(initBindings=...) do not work with a remote SPARQLStore (issue #2055). What I've been using recently is the QueryBuilder from PR #1090. It relies heavily on the n3() function, which seems to perform the necessary (secure?) quoting of Literal and URIRef objects.
