I like the idea of using __ for temporary, transitional, and
experimental keywords.  Using __ has several advantages here:
  - It's unlikely to collide with existing identifiers.
  - You can create as many of them as you want without worrying about
namespace pollution.
  - It's ugly as a reminder that the feature is temporary, transitional,
or experimental.
  - It's easy to search for and easy to globally replace with a real
keyword.

Eventually all features using __ keywords should be removed, renamed, or
modified in such as way that they do not require a keyword at all.
