I think suitable tricks, as being mentioned elsewhere on this thread, will make that kind 
of thing work just fine for my needs.

The only issue is that I don't have anything inserted _after_ the %args.  In particular, I 
can't put a try/catch around them.  Boost.Format throws exceptions if the arguments are 
not good, and since this is for error message generation I want it to be fault-tolerant. 
Really, what I want is to make the format more tolerant, and then this will work just 
fine.  I'll start a new thread on that.
