** all of the above
** reuse the same scratch package whenever a system is reloaded from disk
** rules for system pathname defaulting are not yet implemented properly
** proclamations probably aren't
** when a system is reloaded with fewer components than it previously had, odd things happen
we should do something inventive when processing a defsystem form, like take the list of kids and setf the slot to nil, then transfer children from old to new list as they're found
** traverse may become a normal function
If you're defining methods on traverse, speak up.
** a lot of load-op methods can be rewritten to use input-files
so should be.
** (stuff that might happen later)

*** Propagation of the :force option. “I notice that
(oos 'compile-op :araneida :force t)
also forces compilation of every other system the :araneida system
depends on. This is rarely useful to me; usually, when I want to force
recompilation of something more than a single source file, I want to
recompile only one system. So it would be more useful to have
make-sub-operation refuse to propagate :force t
to other systems, and
propagate only something like :force :recursively
.
Ideally what we actually want is some kind of criterion that says to
which systems (and which operations) a :force
switch will
propagate.
The problem is perhaps that `force' is a pretty meaningless concept.
How obvious is it that load :force t
should force
compilation? But we don't really have the right dependency
setup for the user to compile :force t
and expect it to work
(files will not be loaded after compilation, so the compile
environment for subsequent files will be emptier than it needs to be)
What does the user actually want to do when he forces? Usually, for me, update for use with a new version of the lisp compiler. Perhaps for recovery when he suspects that something has gone wrong. Or else when he's changed compilation options or configuration in some way that's not reflected in the dependency graph.
Other possible interface: have a 'revert' function akin to 'make clean'
(asdf:revert 'asdf:compile-op 'araneida)
would delete any files produced by 'compile-op 'araneida. Of course, it wouldn't be able to do much about stuff in the image itself.
How would this work?
traverse
There's a difference between a module's dependencies (peers) and its
components (children). Perhaps there's a similar difference in
operations? For example, (load "use") depends-on (load "macros")
is a
peer, whereas (load "use") depends-on (compile "use")
is more of a
`subservient' relationship.
