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,
