redefining arg list of clos method
Date: Thu, 7 Feb 91 14:21:06 MST
From: firstname.lastname@example.org (David R Strip )
While developing some clos code I have encountered the
problem that if I
(defmethod foo ((x class)) ...
and then later decide I really want
(defmethod foo ((x class) &optional (more t)) ....
the compiler complains that this does not conform
to the arg list for foo, and none of the proceed optioins
allows the arg list to be redefined. ( This should
be reasonable if the method is only defined for a
single class). The way I currently get around this is
with a defgeneric foo (x more),
I'm surprised DEFGENERIC lets you get away with this.
proceed with the
redefinition, then recompile my method.
Is there a better way around this (short of writing
the arg list correcty the first time :-)
Have you tried m-X Kill Definition? I think it works...
If all else fails, try (FMAKUNBOUND 'FOO). I agree with you that the one of
your options when this blows up should offer to remove all the methods which
do not conform with the new definition.
