Yup - arguably it would be nice to have an overload for vector iterators that does the same thing. > And see https://gcc.gnu.org/contribute.html#legal for why code pasted into > bugzilla without the necessary paperwork is unhelpful (and possibly even > counter-productive if we end up having to re-invent the same wheel without > using your code). I've read it, it says copyright assignments are unneeded for small contributions. Also, this wasn't patch code, just spitballing code. > Indeed. It's a forward iterator.
