Can you have more than one type constraints for T?

While thinking about the assignment at the end I was wondering if something like func myFunc<T: protocol1, protocol2> was possible. So that T has to conform to both protocols.

I was thinking about making T conform to both comparable and equatable(or something).

The following should do:

func test<T where T: Equatable, T: Comparable>(test: T) {}

However, the Comparable protocol already inherits from Equatable, so it's not really a good example.

public protocol Comparable : Equatable {}

Hope that helps :)
