Clearly.

If I was coding a Forth program - which I haven't done - and not
a Forth interpreter - which I have done - then, I likely wouldn't
do some of the complicated stuff that some of the Forth system words
require when coding words for the Forth program.  I.e., I would
most likely use a simpler, more fluid, easier to grasp, perhaps more
factored, method of coding for a regular Forth program.  E.g., some
stack sequences for stack words or loop primitives are generated by
an optimizer and are almost indecipherable by a human.  These are
shorter, faster than more readable definitions.

... as does my Forth.
