Couldn't you use the regex library for string scanning?

I looked at the boost format library "format.hpp".
It is really pretty complete.

But like Andy I would find it very convenient to add the functionality
for
named substitions. Positional parameters are not bad - it's just what
printf does. But if we create a new formating library using C++ we can
even do better.

Yes - there are many ways to do the same thing "string fromating".
Generations ;-) of programmers had the same problem and did find one or
the
other solution.

Another thougt:

By now there's nothing in boost, to do the opposite thing of string
formating -
string scanning like using scanf(), is it?

The main argument for a C++ formating library, I think, is the missing
type
safeness of printf()-like functions using ellipse parameters.

The same is true for scanf(). So here a replacement using C++ might be
equally interesting.
