That's not something we should assume a new D user will know.
Someone with a few years of C++ experience will probably be okay,
but that's kind of my point - the documentation shouldn't require
that background. I can imagine someone seeing examples that use
auto with ranges and then asking "Now what?" Those are the
frustrations that make users give up on the language.
