It's a nice start, but it's far too limited IMHO, since it only defines a
very restricted subset of range types (though it's certainly better than
nothing). I started implementing a more full-featured solution (one which
would allow you to define any combination of range types - bidirectional
with length, without length, infinite, etc.), but I ran into either compiler
bugs or library bugs IIRC, and it fell by the wayside.

Regardless, I think that we should create a general solution which allows
you to instantiate the full combination of range types (as well as
specifying a reasonable subsets for those who want decent coverage but don't
want to test every combination) and which can be used in anyone's code
rathear than just in Phobos.

And perhaps, a package containing a variety of unit test helpers is in
order, where a module handling ranges would be just one of the modules
therein.
