One example could be matrix multiplication.
It's rather trivial but cumbersome operation,
where usually a few transitional variables are
used to maintain clarity of the code.

Probably "bigger" Forth compilers are indeed
already "too good" for the difference to be
(practically) noticeable — still maybe for
simpler Forths, I mean like the ones for DOS
or even for 8-bit machines it would make sense?
I'll try to do a few checks in the days that'll
follow.
