Re: [Bug-apl] How does a vector become a matrix?

[Jay Foad]

APL2's Disclose (Dyalog calls it Mix) will convert a vector of vectors
into a matrix:

      ⊃'timor' 'mortis'
┌→─────┐
↓timor │
│mortis│
└──────┘

Your second application of Disclose is applied to a 1-vector of
1-vectors (,⊂,7), so it returns a 1x1 matrix.
