Re: [Bug-apl] Rank operator and function assignment

[Juergen Sauermann]

Hi,

actually the example below works if you set the parentheses differently:

      {'foo', ⍵}⍤1 (4 5⍴⍳10)
foo 1 2 3 4  5
foo 6 7 8 9 10
foo 1 2 3 4  5
foo 6 7 8 9 10


The reason why your example below does not work is that your parentheses 
force
{'foo',⍵}⍤1 to be computed first (throwing the rank error because of 
argument 1
which is expected to be a vector).
