I think you've done pretty good. Most people try to describe their
problem with their own words instead of providing the facts.

It seems that smanip once was in the ANSI draft for the STL but it
didn't make it in and got rejected.

Actually, the manipulators defined in the `iomanip' header return some
"unspecified" type. So, you can't use them for your own class. But of
course you may define your own manipulators and "<<" operators.
