Actually, being able to get a list of all types conforming to a protocol would solve all the use cases I can think of for this...

It seems you've had this idea before, so it must be good:

Getting a list of protocol conformers

I would like to be able to get, at runtime, an array of all types conforming to a particular protocol. (Similarly, I would like to be able to get an array of all subtypes of a given type). Is this in the generics manifesto? If not, can it be added? What is the timeframe? It seems to me, that the compiler should actually already have this information, and it is just a matter of keeping it around when it is requested. I could be wrong about that though... Why do I want this? It would make …

And here's another related discussion that seems to come to the same conclusion:

Global init() functions

I’m not sure if this was proposed or not; or even if this is a Swift-ly way of doing things. It would be pretty handy to be able to declare init() functions in my module to register handlers. It’s a common pattern in enterprise software. Currently, I have to generate a lot of boilerplate code to emulate the behavior. I think it would be cleaner to have these global init() functions.
