Would it be reasonable for your use case to have MY_FANCY_ASSERT be:
#define MY_FANCY_ASSERT(cond, str) \ if (cond) {} else format(str) % __FILE__ % __LINE__
or similar? It would restrict where you could use it, but would be simple and guarantee the properties you want.
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. —John
