Actually, the reason I wasn't seeing Zach's bug when running in SLIME is because
I was running my asdf on top of the require'd asdf; now since
input-files is not included
in the list of redefined-functions, I was still benefitting from a
method from the previous
ASDF that explicitly overrode the default method, forcing modules to
actually have no
input-files. So it was actually my bug to have deleted this method instead of
making it a method on parent-component. There. Mea culpa.
