Not really, unless you've noticed something I missed. Some objects in
the environment (class definitions in particular) have an extent
corresponding to the duration of the invocation of COMPILE-FILE, but the
environment objects themselves, as received by a macro, do not need to
be used outside the extent of that macro invocation.
