The current tuple output mechanism wants me to say

cout << formatting_manipulator << tuple;

The expression (cout << formatting_manipulator) return an "embossed" cout, 
but currently it returns just cout with internal settings modified.  The 
call must change things allocated within cout, like the standard 
manipulators do; although it is supported by the standard output, I find 
this approach so CFront-ish.

How about using the syntax (cout << format_specification (tuple)) instead?

Or even (cout << tuple / format_specification)?
