At least on x64 and CISC CPUs, calling a deferred word is just
  CALL [] foo
rather than
  CALL foo

The difference on x64 is one byte and a a few (hardware and cache
dependent) cycles.

IMHO Forward referencing and resolving words are likely just to be
wrappers for syntactic sugar around DEFER and IS.
