You are right, this benefit of classes doesn't apply here.

Ok, no matter what the outcome is, I'll see if I can write a
simple file logger that I can use in RAII struct dtors (where
neither allocations nor throwing seem to be an issue) and that
has a fallback to writing to stderr. I wrote earlier that I
would want a fallback logger if writing via the network fails
or the disk is full, but maybe this logic can be implemented
inside a logger implementation. I haven't actually tried your
API yet!
