if asdf were to adopt an 11.1.2.1.2-rule, asdf-ecl.lisp would

it would not be supported for an extension to extend 'asdf:load-op

method which forced complete traversal results. it would be be
necessary to specialize the load-op class as, for example, collect-
op, and specialize operation-done-p on that class. in which case
its own primary method could always return nil and an :around
method would not be necessary.
What you suggest can not be done.
you type too fast.
please see my next message.
While load-op dependencies are automatically added to all systems
by some hard-coded logic in DEFSYSTEM, if we create a collect-op,
traverse will not find any dependencies that are related to it and
it will refuse to, say, traverse cl-ppcre when stumpwm depends on it.
A potential aternative would be to remove the :around method and
use *forcing* but this again does not work, because *forcing* only
forces the system we act upon, and not the dependecies it has.
So right now there is no way to traverse the ASDF system tree
without such a hack.
