Or, we might get a bad design that has not been vetted by adoption in
a large number of systems and programs (LOCALS| anyone?). And the
definition of common practice by some ("It is common practice if it is
implemented in my Forth system and is used by my customers") does not
quite cut it, as the LOCALS| example demonstrates.

The difference is that you cannot remove individual words from
wordlists, while you may want to remove individual recognizers; e.g.,
you may have a recognizer for 20:48:25 meaning time in one place, but
something else in another place. And even more so with really
domain-specific notations.

That's a good point.

Yes, that's one idea I had: recognizers behave like wordlists, except
that they cannot be used in SET-CURRENT. That would avoid the need
for having a separate recognizer stack. But what's not yet clear to
me is how to integrate that with the current search order, in
particular if a program sets a given search order explicitly.
