Hm.. from that link you sent, look up a bit, you see this interesting 
tidbit:

struct IndexedBy(R, string I_ = "Index") if (isArray!R && I_ != "I_") // 
prevent strange bug from occurring

That comment seems to be similar to what you are talking about...

Later, there's this:

auto indexedBy(string I, R)(R range) if (isArray!R && I != "I_") // 
prevent strange bug from occurring

Should that be change to "string I_" also?
