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.
