I am having difficulty finding reasons other than tradition that a length
should be allowed to be a list.
badlength =. $
mean =. +/ % badlength
$ mean"1 i. 5 5
5 1
Of course, J already does the right thing by providing # . It might be in
the spirit of J to continue to correct mistakes made in APL by correcting
the documentation for take.
