i applied the second part of that patch. as for the names of the
charset i'm just going to leave the final clause, whatever keyword is
passed to encoding-keyword-to-native will be intrened into the charset
package. if you have the required encoding good, otherwise it's not
really arnesi's problem to figure out how to handle this. i do not
like the idea of silently converting one encoding (utf-16) into
another very similar but different (ucs-2), i think that's just asking
for some really hard to find bugs.

there's a call to with-call/cc in backtracking.lisp, with-call/cc
macro expands into a literal occurence of (among other things) an
instance of application-form. however, when backtracking.fasl is
loaded arnesi (and therefore application-form) should already be
loaded. what happens if put 

(eval-when (:compile-toplevel :load-toplevel :execute)
  (finalize-inheritenc (find-class 'application-form)))

after the defclass form which define application-form? (in
arnesi/src/walk.lisp).
