[swift-evolution] [Pitch] Extend Any.Type to allow construction of bound generic types

I often find myself needing to construct an instance of a bound generic type at runtime, in much the same manner as I would a "standard" type.
As for a standard type…
let aType = Int.Type
let anInt = aType.init(0)
I also want to be able to use the same mechanism for a generic type…
struct MyStruct<T: Equatable /*, etc */>
var value: T?
let paramType = // type from streaming or reflection compliant with Equatable
let structType = MyStruct<paramType>.self
let f = structType.init()
At present, the following compiler error is raised…
'paramType' is not a type
I am the only one to require this behaviour? If not, do we want a proposal? If so, could you let me know your views on its worthiness?
