Re^5: How do I prototype a function with a varying number of arguments?

Instinctively, I think maybe this is a trick question, but, nonetheless....like this?

&sub ($@[0], $@[1])

I mean, technically a reference to a single array element is a scalar variable, so, that would work then....right?

I think maybe this is a trick question... How do you pass the contents of a two-element array to an unprototyped function which takes two scalar arguments? `some_func( @two_elements );` How do you pass the contents of a two-element array to a `$$` prototyped function? `some_func( $two_elements[0], $two_elements[1] );` That looks less generic to me, as it forces callee details to the caller side.

some_func( $two_elements[0], $two_elements[1] );
