My understanding is that Richard is concerned about ambiguities, perhaps
not even flagged as errors at load time, that occurred in a version of
CL packages he implemented or otherwise worked with in the past, but
that may no longer occur in Common Lisp implementations conforming to
the newest standard. I believe he described the "misfeature" he is

It's an optional feature that shouldn't be used -- much like -rf to rm or
really any flag to any program -- if you one doesn't understand what it does.
It will error and offer restarts if two used packages export symbols with the
