--- Comment #10 from Stewart Gordon <smjg@iname.com> ---
You completely forgot to post the compiler output.  Here's what I get (DMD
2.065 Win32):

bz10189.d(8): Error: cannot implicitly convert expression (c) of type
SortedRange!(int[], (a, b) => a > b) to SortedRange!(int[], (a, b) => a > b)

But the two types are the same.

The same occurs when a D1-style function literal is used

----- bz10189a.d -----
void main() {
    import std.range;
    SortedRange!(int[], "a > b") a;
    SortedRange!(int[], "a > b") b;
    b = a;
    SortedRange!(int[], function bool(a, b) { return a > b; }) c;
    SortedRange!(int[], function bool(a, b) { return a > b; }) d;
    d = c;
}

--- Comment #11 from RazvanN <razvan.nitu1305@gmail.com> ---
We now have traits(isSame) that can perform a primitive form of lambda function comparison. This can now be implemented in the opAssign of SortedRange so it's not a compiler issue anymore. Changing component to phobos.
