We wonder if people have a view on which of the following is clearer/better:
1. except *E as e:  //  except *(E1, E2) as e:
2. except* E as e:  //  except* (E1, E2) as e:
(The difference is in the whitespace around the *).

At the moment * is a separate token so both are allowed, but we could change that (e.g., make except* a token), and in any case we need to settle on a convention that we use in documentation, etc.
It is also not too late to opt for a completely different syntax if a better one is suggested.
