I'm not sure about the name SizedIteratorRange. Maybe IteratorRangeWithSize? Maybe something more abstract, like Container?

[Sam Weinig]

Maybe SizedContainerProxy?

I’d like the type here to be OptionContainer::ValuesIteratorRange. Can we add some "using" to HashMap.h so we can do it that way instead of having to write out the type like this?

Ditto.

> Source/WebKit/UIProcess/WebProcessProxy.h:101
> +    WTF::SizedIteratorRange<WebPageProxyMap, WebPageProxyMap::const_iterator::Values> pages() const { return m_pageMap.values(); }

And again.

Or is there some way to use std::result_of?

I went with the type aliases. No need to make the caller user do something weird.
