I have some code along these lines:

                string toString() { ... }
        }
        ...
        S s;
        writeln(to!string(s));

In dmd 2.059 (I believe) and earlier, this calls S.toString(). However,
in git dmd, this calls data.toString() instead.

I'm just curious about the rationale for this change, and whether
there's a way to override the toString() call so that it always calls
S.toString()?

Just a guess: It could be related to const-correctness improvements. Try 
defining S.toString() as const.
