The operators whose value is not a function of the solution mapping they are evaluated on, so that two
evaluations of one expression may disagree. NOW is deliberately absent - "all calls to [it] in any one
query execution must return the same value" (SPARQL 1.1 §17.4.5.1) - where BNODE is present because
§17.4.2.14 fixes a blank node per solution mapping and argument.
