It appears to me that E. on multidimensional arrays fails when x has a different numeric type from y:
(,: 0 1) E. i. 4 4 NB. Error, Boolean x, integer y 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (,: 0 1 2) E. i. 4 4 NB. OK, Integer x, integer y 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (,: <. 0.1 + 0 1) E. i. 4 4 NB. OK, Integer x, integer y 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Looks like it's OK on lists.
