I'm basically glad to see the Type suffix removed from the standard library protocols. I'm hoping that they'll have a solution to make it so writing a function over a generic sequence isn't such a mouthful.

I'm a little flummoxed by the new effort for first argument labels. Function names often imply the meaning of their first arguments very effectively and the new splits in function names seem arbitrary at times. Labeling subsequent arguments is an excellent feature of Swift but first argument labels often seem to complicate the syntax, especially labels like of: which don't always imply much about the meaning of the argument by themselves.
