Doing it right requires introducing new kinds of nodes in the dependency graph for loading asd files, and rethinking how we track defsystem-depends-on dependencies as well as direct load-system statements in .asd files. If you're willing to do it, I'll be glad to provide guidance and code review. I'd also like to kill the current parse-defsystem code inherited from ASDF 1 to replace it by something that relies less on side-effects, but I'm not sure how to do it in a way that doesn't break backward compatibility with some hidden assumption that I don't know about. A quick mucking around with the code revealed too many strings to pull — though most of them related to the above defsystem-depends-on issue. > I can definitely add inheritance of other things, but I'm not sure what > makes the most sense.

Maybe version is useful, so you can have version constraints on a secondary system without having to depend on the primary system, when the secondary system doesn't depend on the primary. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Long live consumership, which is individual and responsible choice!
