Hey, that's pretty cool. I'm glad to see the ability to format items
inside of a container as well. It should handle maps and pairs
reasonably well. I think that I have the same complaints about this as
io_manip
The saving of information to the stream means that you can affect all
future output...
For instance, if you have a type
map<custom_object, list<string> >
and custom_object's stream output uses io_format<list<string> >, then
you are going to run into trouble if it wants a different formatting.
I don't know the right way to solve that problem though.
