Yes, "literal" would be fine to me, though I feel that people might
not exactly understand what "exactly" means :)

I agree. It may be more powerful, but I think there is a benefit to
keeping it simple.

That is my opinion as well. What I have in mind really is a direct
supplement to meet what the scanf() family can do with format strings
that include more than just the format specifiers, but I am not sure
if turning this into an input stream version of Boost.Format is a good
idea, so I shall stick with proposing a manipulator for now.
