Forth-2012 (and -94) says:

|13.3.3.1 Compilation semantics
|
|d) Separate sets of locals may be declared in defining words before
|DOES> for use by the defining word, and after DOES> for use by the
|word defined.

I.e., the following is standard:

: foo 
  create {: A :} \ A visible here
does>
  {: B :} \ B (and only B) visible here
;

Whether systems other than Gforth implement this correctly I have not
tested.
