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.
