Is there a way to write an `if case` statement as an expression?

Question

Consider this code:

enum Type {
    case Foo(Int)
    case Bar(Int)

    var isBar: Bool {
        if case .Bar = self {
            return true
        } else {

I have a similar wondering, and I kept searching for some work arounds about this, and landed on this page. I came up with code like this to compromise.

fileprivate enum TypePrimitive {
    case foo
    case bar
}

enum Type {
    case foo(Int)
    case bar(Int)
    fileprivate var primitiveType: TypePrimitive {
        switch self {
        case .foo(_): return .foo
        case .bar(_): return .bar
        }
    }
    var isFoo: Bool { self.primitiveType == .foo }
    var isBar: Bool { self.primitiveType == .bar }
}

I hope Apple will provide better solution by adding some features in Swift language.
