Yes, I mostly think of this for debug output. But that does come up
a lot. Similar to debug output would be testcase output. Something
the customer still does not see, but is certainly useful. An example
of something in production code might be printing a container out as
an html table.

In BoostCon 2007, we wanted something that worked like 'print(c)' where
'c' is any container. Other languages have this capability. We did
consider using Karma during that conference and somebody presented
this. It was decided to not be simple enough. The code samples you
provided are compelling, but it's not as dead simple as 'print(c)' or
the more C++ oriented 'cout << c'.
