swizzle
     
        To convert external names, array indices, or references within
        a data structure into address pointers when the data structure
        is brought into main memory from external storage (also called
        "pointer swizzling"); this may be done for speed in chasing
        references or to simplify code (e.g. by turning lots of name
        lookups into pointer dereferences).  The converse operation is
        sometimes termed "unswizzling".
     
        See also {snap}.
