[Boost-users] Boost.Format

I'm using Boost.Format as a simple way to create strings to pass to exception constructors and primitive logging output during debugging (Windows' OutputDebugString).

I see that the format object can be inserted into a stream, easily.  But, with arguments, it's awkward to convert it to a string -- you need extra parens around the whole thing.

Is there some good reason why there is no implicit conversion to string?  E.g.
          string message= boost.format("blah") % argument % errorcode;
          OutputDebugStringA (message.c_str());
          throw std::runtime_error (message);

Or, is there some simple way that I'm missing?

Thanks,
