Since the inverse of q: is */ you may reduce */@[EMAIL PROTECTED]: to

I still don't understand why monad { produces boxes; perhaps to be
consistent with its (necessarily) boxed input? In this case consistency is
a hindrance; in almost every use I've seen (including this one) we open the
result of { in the end.
Moreover, the boxes conflict (in my estimation) with the spirit of J, where
homogenous rectangular arrays are the norm, and boxes only used for the
exceptions, where homogeneity and rectangularity is not an option. But, by
definition, >@{ is homogenous and rectangular.
(Of course I understand that we are now constrained by backwards
compatibility)
