We need to complete action on cast.hpp and the other libs currently
marked as "beta", and then close down the beta section.

I think that means doing two things:

1) Someone (Kevlin, Steve, Jens?) needs to provide the final code and
docs for stream_casts. Could I suggest stream_cast for the checked
version, and unchecked_stream_cast for the unchecked version? The
undecorated name should be the safest version.

2a) Remove implicit_cast entirely. Add a comment to the docs saying
to use static_cast.

2b) Replace implicit_cast with unchecked_numeric_cast. See Darin
