What problems does it actually cause ?
It causes having to maintain this weird system, having functions and classes the symbols of which become inaccessible, etc. It causes users having the wrong expectations and/or having to learn some magic semantics that do not apply to other cases. If someone wants first class lexical namespaces for CL, let them do it the right way. A half-assed "solution" special-cased to .asd files. It's not a major big deal, but one more cleanup I want to make on the way to ASDF 3. I appreciate Dan Barlow having made various experiments when he wrote ASDF; some of the experiments were successes, other were failures. Successes: * User-extensible methods specialized on the dual operation and component class hierarchy. Big big win. * moving pathname management out of individual system files into asdf itself. Big big win. * Using TRUENAME to simplify .asd management with a link farm. Big win at the time, though ultimately not scalable. * Restarts :around compilation and loading (dunno if mk-defsystem did that). Win. Failures: * not propagating timestamps at all (failure inherited from mk-defsystem). Big fail. * having some dependencies implicit via the clunky TRAVERSE algorithm in general. Related fail, though still not worse than mk-defsystem. * the run-shell-command dead-end (inherited from mk-defsystem). —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org There is a difference between knowing the path and walking the path. — Morpheus, in "The Matrix"
