[intro.multithread] mentions lots of things like: A release sequence ... is a maximal contiguous sub-sequence of side effects I know what a /visible/ side effect is (see #13), but that doesn't tell me what a side effect is in the first place. I assume that a "side effect" is just a write (e.g. "a = b" has a side effect of modifying a), but AFAICS the N3376 has no language to support that assumption. Am I right? Should I submit a defect report? Thanks, Andy -- [ comp.std.c++ is moderated. To submit articles, try posting with your ] [ newsreader.
