[asdf-devel] Directly loading "/home/etc/etc/system.asd"

Hi all, Is there a way to load a system directly, leaving everything else (source-registry configuration, *central-registry*, or what not) alone? I hacked up something to do this, (asdf:load-system #P"c:/blah/blah/cl-ppcre-1.2.19/cl-ppcre.asd") so that there's no need to worry about specific versions or setting up paths to a specific library. If the library being loaded depends on other modules, then we return to searching the source-registry as if by typing this before loading our system: (asdf:load-system <lib-depended-upon>) Does asdf already support this? Will such a feature be useful? Yong.
