And what is the correct answer?

I tried it with APL/X 5.1, and i get the same “RANK ERROR” as in GNU APL.

If i understand disclose correctly, the right argument are nested elements, but of a shape that allows for them to be laminated into a matrix as a result. Having a scalar, a vector and a matrix is bound to create difficulty.

The following _expression_ should work, if I'm reading the ISO spec correctly:

⊃ 3 (1 2) (2 2 ⍴ 0 1 2 3)

It does work on Dyalog, and gives the expected result.
