#### 2.6`` Locations: #%variable-reference

(#%variable-reference id)
(#%variable-reference (#%top . id))

Produces an opaque value representing the location of id, which must be bound as a top-level variable or module-level variable.

The result is useful to low-level extensions; see Inside: PLT Scheme C API. It can also be used with variable-reference->empty-namespace, variable-reference->resolved-module-path, and variable-reference->top-level-namespace, but facilities like define-namespace-anchor and namespace-anchor->namespace wrap those to provide an clearer interface.
