/**
* Reification Done Right test suite.
*
* The basic extension is:
*
*
* BIND(<> as ?sid)
*
*
* This triple reference pattern associates the bindings on the subject,
* predicate, and object positions of some triple pattern with the binding on a
* variable for the triple. Except in the case where ?sid is already bound, the
* triple pattern itself is processed normally and the bindings are concatenated
* to form a representation of a triple, which is then bound on ?sid. When ?sid
* is bound, it is decomposed into its subject, predicate, and object components
* and those values are bound on the triple pattern.
*
* When there are nested triple reference patterns, then they are just unwound
* into simple triple reference patterns. A variables is created to provide the
* association between each nested triple reference pattern and role played by
* that triple reference pattern in the outer triple reference pattern.
*
* We can handle this internally by allowing an optional named/positional role
* for a {@link Predicate} which (when defined) becomes bound to the composition
* of the (subject, predicate, and object) bindings for the predicate. It might
* be easiest to handle this if we allowed the [c] position to be optional as
* well and ignored it when in a triples only mode. The sid/triple binding would
* always be "in scope" but it would only be interpreted when non-null (either a
* constant or a variable).
