re: . . . and from what I have seen, compute-applicable-methods will
return the correct value only after its generic function argument has
been called at least once. Thus, allocate-instance, initialize-instance
and shared-instance must be called once before make-instance will
recognize method arguments as valid initialization arguments. This
seems to be a bug.
I don't think this is correct. COMPUTE-APPLICABLE-METHODS only needs to
see a satisfactorily rich subset of the total effective methods for that
generic-function. I think it will force the calculation (or re-calculation)
of the current effective methods when necessary, regardles of whether or
not the function has been 'called'.
Initarg validity checking needn't actually call COMPUTE-APPLICABLE-METHODS,
but that is another issue.
