[swift-evolution] [Pitch] Rename `x.dynamicType` to `x.Self`

I'm just concerned about the obviousness of it. If what we are doing is just grabbing the type, why couldn't it be:

someClass.Type (like in the generic system)

I'm open to Self, but I just want to make sure we exhaust all avenues that are more obvious at a glance:


SelfType is redundant but it also more obvious at first look. 

Maybe it doesn't matter and I am caring about the looks of it too much. Because so many people seem to support .Self in this thread, it might just be me and something I need to accept :P
