Is this really all that hard?  I'm thinking it could be implemented by
using the real C sprintf underneath, passing one % specifier and its
corresponding parameter at a time, coerced to whatever the conversion
specifier specifies.

The only thing that breaks this idea is the $n positional specifiers, I
think.
