There's (get-var-pointer '*s-s-ch*) but it's not much better, I agree. We could have DEFCVAR define a symbol macro for &*S-S-CH* that would get the pointer, maybe? For nesting, one can use FOREIGN-SLOT-POINTER explicitly or the (:pointer foo) for WITH-FOREIGN-SLOTS. What do you think? -- Luís Oliveira http://kerno.org/~luis/
