[Bug-apl] Each first

[Daniel H. Leidisch]

Hello!

Each first of a nested lists behaves weirdly.

      ↑¨(1 2) (3 4)
1 3
      ≡↑¨(1 2) (3 4)
1

So far so good, but:

      8⎕cr ↑¨(1 2) (3 4)
┌→──────┐
│┌─┐ ┌─┐│
││1│ │3││
│└─┘ └─┘│
└───────┘
      (↑¨(1 2) (3 4))⍳3
3

This works (i.e. returns ⎕io+1) in NARS2000 and NGN.


Regards,

Daniel
