Re: [Bug-apl] 8⎕CR on empty string array prints str ange result

[Nick Lobachevsky]

The difference is that a is an empty nested array and that b is an
empty simple array.  The depths would be different.  I tried this
example on Dyalog and ≡a is 2, one level of nesting, while ≡b is 1, a
simple vector.
