Hmm...
We could probably do with a denser way of expressing code. (I can
think of several possibilities here.)
But, also, I ran into a problem testing this:
mean =: +/ means %
(007) noun result was required
(007) noun result was required
meang =: */ means (%:~)
(007) noun result was required
(007) noun result was required
meanh =: +/@:% means (%~)
(007) noun result was required
(007) noun result was required
FYI,
