      Oh, so it returns the sine of the number of elements passed to the function, right?

      And you didn't even know bears could type.

        You could say that, but I think it's more accurate to say that the function doesn't receive any more than one element. The array in sin(@_) is evaluated in a scalar context. Its value in that context is the number of elements in the array, and that single value is given to sin.
