Not necessarily. I think, you can leave std.algorithm string-agnostic and special case string operations in, say, std.string, which will take and return regular string types, but internally call std.algorithms on dchar range wrappers, this is what std.algorithm does now, I suppose.

I think we just want to do string operations. I believe, java and .Net live fine with String classes and string operations built into them.
