namespace collisions

In Haskell, if you import packages X and Y, and X contains a symbol
"foo", you can refer to it as just "foo" or explicitly as X.foo.

If both X and Y contain foo, then saying just "foo" is ambiguous and the
compiler flags it as an error.  You are required to say X.foo or Y.foo
to indicate which one you want.

Is there a simple way to do something like that in Forth, to get an
error or at least a warning, if the same symbol occurs in multiple
wordlists in the search order?

Thanks.
