we also have a (def package ...) that allows for specifying a readtable setup form for a package that is used by the custom in-package macro, and also updates the internal swank mapping when the hu.dwim.def+swank asdf system is loaded.
I'm interested in this. I need something like this atm. Is it available somewhere?
it's in quicklisp, and if you prefer repos then it's also available at http://hub.darcs.net/hu.dwim
you need to load hu.dwim.def+swank.
if you just want to copy the machinery, then the key part is in integration/swank.lisp
hth,
