Re: defgeneric :method option

Another argument for removing methods first is that when a method is added, but
it is shadowed by a method to be removed, the generic function is in as much of
an inconsistent state as when a method is removed and there is no method for a
particlar set of arguments.
It seems to me that doing the remove-method first answers Patrick's issue, and
provides no more inconsistency.
The case I had in mind is the one where the defgeneric has the same :method
options both before and after.
