swizzle

swizzle v.  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}.
