3.4 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 only to low-level extensions; see (part "inside-mzscheme").
