Use fooR in place of your first foo:
fooR0 =:2 :0
0 (m foo n) y
:
''
)
fooR=:2 :0
(m fooR0 n)"0 1 0
)
And, use fooD in place of your second foo:
fooD0 =:2 :0) (0&$: :)
0 (m foo n) y
:
''
)
fooD=:2 :0
0&$: : (m fooD0 n)
)
This is somewhat roundabout, which I understand is not ideal.
On the other hand, this works with current versions of J, which
seems like a good thing.
