How else can you make a user-defined dec() work?

The example I gave in the other thread shows how to not need to rewrite the 
format string.

But even if you did rewrite it, it doesn't escape the template function, and can 
be RAII'd.

Dealing with a string allocated and returned by `dec()` is significantly harder.
