Hi Blake,
thanks, fixed in SVN 290.
As far as ⍕ is concerned there seems to be no right or wrong.
The IBM APL2 language reference contradicts itself (e.g. pages 135 vs.
136 for nested values)
and the ISO standard always wants a result rank ≥ 2 while IBM sometimes
gives rank = 1.
I have tried my best to make sense out of that.
My approach was even different (rank 1 for one-line output and rank 2
otherwise) but now
it should be a little closer to IBM APL2.

The final result should have been:
