Re: [Bug-apl] ,[2]/Matrix returns a syntax error

[Juergen Sauermann]

Hi Alex,

I would say that this is illegal syntax if we look at the ISO standard, but it seems to work in
IBM APL2. I will try to make it work in GNU APL as well. In the meantime you can do this:

      {⍺,[2]⍵}/A A

1 2 1 2 1

2 1 2 1 2

1 2 1 2 1

2 1 2 1 2

      ,[2]/A A

SYNTAX ERROR

      ,[2]/A A

Even parenthesis don't work:

      (,[2])/A A

SYNTAX ERROR

      (,[2])/A A
