Eh, I'd have to go back through the github history :-(

The idea goes way back. Matthew Wilson and I were thinking about how to do C++ 
STL-like iterators, which were based on a pointer abstraction. I thought it was 
natural for D to do it as an array abstraction. There are some posts about it in 
the n.g. somewhere. The idea languished until Andrei joined us and figured out 
how it should work, and ranges were born.
