Yes, of course.

No, I think the shape of the funcallable instance function is fine - it seems to take arguments just like the generic function just fine.

I think it's rather this (but I'm still testing this):

Index: src/c/gfun.d
===================================================================
RCS file: /cvsroot/ecls/ecl/src/c/gfun.d,v
retrieving revision 1.49
diff -r1.49 gfun.d

What happens is that after a set-funcallable-instance-function the slot-value functions don't work on the generic function anymore...
