Keith got my drift.  remove could (and does) return a copy of the vector
with the argument element removed.  I was thinking that remove-key would
remove the element at a particular index, but that is not consistent with
the contract of remove-key (because the key would still exist, except for
the case of the very last element).

Perhaps what I want is the ability to insert and delete at a particular
index (key) in (implicit-key-collection) sequences.  I don't see such
functionality specified in the DRM, but perhaps it is in a library?
