Bug in grid:copy permutation: missing call-next-method
In data/permuations.lisp
grid:copy permutation
calls call-next-method
. This causes failures in some tests.
An example from tests/permutation.lisp makes a copy of a permutation into a lisp array
(LET ((PERM-1 (MAKE-PERMUTATION 4 T)))
(GRID:COPY-TO PERM-1 'array 'fixnum))
It is not clear what the call-next-method should be
