''A function with a fixed number of arguments'' gets special treatment in J when the fixed number is 1 or 2. <lang j>f 'one argument'</lang>and <lang j>'this example has two arguments' f 'the other argument'</lang> Alternatively, you can add something that enforces a constraint on length for the varargs case. |
