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".
