While I still have some TODO notes of my own to resolve before posting it to python-ideas, the examples section at https://github.com/ncoghlan/peps/pull/2/files#diff-7a25ca1769914c1141cb5c63dc781f32R202 already gives a pretty good idea of the differences relative to PEP 572: rebinding existing names is unchanged from PEP 572, but introducing new names requires a bit of "Yes, I really do want to introduce this new name here" repetition. The big difference from previous iterations of the "given" idea is that it doesn't try to completely replace the proposed inline assignments, it just supplements them by providing a way to do inline name *declarations* (which may include declaring targets as global or nonlocal, just as regular function level declarations can).
