I agree; in fact why aren’t these properties on the type itself? The type is what matters; why can’t the type just tell me it’s size? 
Having free functions or magic operators seems to be another holdover from C. 


    let x: Any = 5
    type(of: x).size

The compiler should be able to statically know the first three values and inline them. The second is discovering the size dynamically.
