The design of the D ranges and algorithms owe quite a lot to C++, 
and I've heard Andrei say as much. Stepanov did the hard work of 
defining common algorithms in terms of iterators of different 
strength. Given that starting point, ranges of different strength 
are an "obvious" next step that many people thought up 
independently. D took it one way and C++ went another.

When designing my range library, I looked at all the prior art 
available to me including D ranges and decided D's path was not 
the right one for C++. My work is based on Boost.Range. I only 
posted here to clear up what appeared to me to be confusion about 
that.
