Yes, I have read your messages, and I think it's a good idea to make
a common frame for all manipulators, instead of the std
manipulators that are of unknown types.

right. 
Notice this would not interfere with a 'manip' function, that
encapsulates whatever you pass it into a 'manip_wrapper'

If the iomanip templates you propose are accepted, we will add
an overload to operator% to enable the example above.
But a manip function would still be useful, for instance if you want to
use custom manipulators, or manipulators coming from a third-party
library..
So even with iomanip<T>, an explicit way of passing manipulators can
still be useful.

BTW,
I think the iomanip would make a useful library. (I'm sending a reply to
your initial message of January 6. Late is better than never.. :-)
