I'd like to distinguish between concrete types and more abstract ones like protocols. A suffix like "Type" is best what I can think of (now).
There is at least one thread which discusses the use of protocols with associated types as (abstract) generic types.
let collection: CollectionType<Element == Int> = [1, 3]
So a differentiation between concrete and abstract types is preferable in my opinion.
This could also be a language feature rather than a convention.

>> They're attractive nuisances. Someone wants an integer type, sees Integer, tries to use it, and suddenly they're getting weird errors about Self and associated object requirements. Or they want a boolean variable, see Boolean, and suddenly their one-bit value is wrapped in a 40-byte protocol witness. Nobody is going to mistake Integerlike or Booleanlike for a concrete type and use it accidentally.
