I added a flag to the Kawa reader, so it returns mutable pairs when called
directly by the read procedure, but returns immutable pairs when called by
"the parser" (i.e. when reading expressions to be compiled/evaluated).  This seems
a workable solution: specifically quoted lists get read as immutable pairs.
