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. Juanjo -- Instituto de Física Fundamental, CSIC c/ Serrano, 113b, Madrid 28006 (Spain) http://tream.dreamhosters.com
