(SVN? You mean git?)

The problem is length() is an auto-return function, and somehow typeof() cannot
find the return type from this function:

--------------------------------------------------
import std.range;
struct X { @property auto length() { return 0; } }
pragma(msg, typeof(X.init.length));   // ()
--------------------------------------------------

Because of this, is(typeof(X.init.length) : ulong) cannot be true, and return
hasLength returns false.

This is more a DMD problem than a Phobos problem.
