[Jprogramming] Inconsistency?

[Henry Rich]

You've not spotted the right difference.

It's not that 'r' has length 1 while 're' has length 2.  It's that 'r' 
has rank 0 while 're' has rank 1.  When you change the rank of the 
argument you change the rank of the result.

To make your program behave the same on atoms as on 1-atom lists, apply 
, to the argument:

    $ (,'rebe') e./ "1 0 i. 2 5
2 5 4
    $ (,'r') e./ "1 0 i. 2 5
2 5 1
