I don’t see how the latter has any advantage over your earlier suggestion [more or less]:

	if (!foo)
		foo = @“Something”;

Admittedly, it takes two lines instead of one. OTOH, as I said in another recent thread, it seems to me that for a *reader* of the code, the latter form is far more accessible than code with the “?…:” operator, which tends to force the reader to figure out if the code is correct or not. I note that in this thread, like the other one, most of the discussion has basically been about figuring out what’s actually correct. Is there *any* confusion over the “if” version?
