I'd say in any case that it's not too difficult, but one line seems
overoptimistic.  Particularly, you need something like (LOCAL) in the
VM.  The rest is just some extensions to the colon compiler.  Your
mention of it taking 3-4 screens sounded within reason to me, and I
don't consider that to be a lot of code.

IMO locals only make sense if you can at least additionally handle
floats and dynamic strings, preferably also structs and arrays.
Such an implementation is certainly not trivial.

Second that. iforth sports not only LOCAL (values), but also
FLOCAL DLOCAL DFLOCAL. You end up establishing a whole menagery
of shadow Forth words.

It is much simpler to allow definitions in a [ .. ] sequence.
