It’s documented in the info page of gnu apl.  A feature (bug?) of the parser 
treats / as an operator in this case.  Simple workaround would be

      3 0 2 ∘.{⍺/⍵} 5 1 7
 5 5 5  1 1 1  7 7 7 
                     
 5 5    1 1    7 7   

I have too limited experience to say whether it is good or bad.  Perhaps the 
parser should accept some exceptional cases?

Best,
