I'm reluctant to add more code unless there's a demonstrated need for
the functionality.  I'd remind everyone that ASDF has ballooned in size
and for all our efforts that inevitably means it has collapsed in
maintainability!

If you'd like an extension to provide either introspection or
"mutabilification", please file an enhancement ticket.  But unless you
provide a use-case with it, it is likely to get short shrift.

Certainly I don't want to hold the 3.1.5 release any longer for such an
enhancement.
