The argument to sin is in scalar context (it has a prototype of "`_`").	[reply] [d/l]

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.	[reply]

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.	[reply] [d/l]
