IMHO, the typed locals are quite im****tant, and can offer a way to be used
for more complex locals (like structures and other sort of tem****ary
buffers).

In bigFORTH, I've the following types:

W:      normal word, the default if no type is selected
F:      floating point number
D:      double number
R:      Record. Usage R: <record_name> <local>. Records are always
uninitialized.

I think this is universal. Whatever buffer you need, you can always define
a
structure/record for it, and declare a local to hold it.
