Thank you.
Forgot to mention scalar extension. When a scalar is supplied as an
argument, it's lengthened to match the inner dimension of the other
argument.
(3 4⍴'cattrattfatt') +.= 't'
2 2 2
(3 4⍴'cattrattfatt') +.= 'tttt'
2 2 2
'a' +.= 3 4⍴'catratfatbat'
1 1 1 1
'aaa' +.= 3 4⍴'catratfatbat'
1 1 1 1
If both arguments are scalar (a silly case) then it would be same as
if only the second function was used.
