PyScript should have a clear definition of what works and what does not

It should be as easy as possible to tell a user what is supported by PyScript. Individual caveats like "foo =bar or 3 is dangerous" should be reduced where possible.

Similarly, with #104 (i.e. in performance mode), it should be clear what is the supported feature set.
