Hi Jürgen:
If my memory is (still) correct it did give SYNTAX ERROR on Sharp APL.
(I recall it because I was once tasked with doing some heuristics to speed up outer product.)

Hi,

even though outer product dates back to the early days of APL, if I remember correctly then
you could only use it with scalar functions, not with mixed functions at that time.

Therefore I believe that ∘./ would have given a SYNTAX ERROR even in the early days
(mainly because you would have needed nested arrays to represent the result).
