I remember about a year and a half ago, there was talk of defining a
wrapper module around ranges to make them more usable in cases where
templates can't be used, such as virtual functions. I've revisited that
now that I'm cleaning up ranges. I've created a fairly simple attempt
at writing such a module. (http://pastebin.com/aDew6Kgg) This exercise
has reinforced my conviction that about the only thing good about
nominative typing is that it's easy to implement efficiently.
I decided to exclude ref access to elements and infiniteness propagation
from the interface entirely because I couldn't see a good way to
implement these. I did, however, include assignable elements. Please
review this module and tell me whether it looks worth including in
Phobos and if so, where. Also, any suggestions on better naming would
be greatly appreciated.
