Great news!  It would be nice now that we're all using C++11 to have something in the style guide about providing C++11-friendly iterators.  Currently, we have a lot of classes that implement foo_begin() and foo_end() methods.  It would be nice to have a common pattern for moving these under an inline class that implemented begin() and end(), so instead of having to do:

for (auto I=X.foo_begin(),E=X.foo_end() ; I!=E, ++E) {
	auto V = *I;
	...
}

We could do:

for (auto V : X.foo()) {
	...
}
