     Thanks @muggenhor.
 
+-   Added an experimental `nested_formatter` that provides an easy way applying
+    a formatter to one or more subobjects while automatically handling width,
+    fill and alignment. For example:
+
+    ```c++
+    #include <fmt/format.h>
+
+    struct point {
+      double x, y;
+    };
+
+    template <>
+    struct fmt::formatter<point> : nested_formatter<double> {
+      auto format(point p, format_context& ctx) const {
+        return write_padded(ctx, [=](auto out) {
+          return format_to(out, "({}, {})", nested(p.x), nested(p.y));
+        });
+      }
+    };
+
+    int main() {
+      fmt::print("[{:>20.2f}]", point{1, 2});
+    }
+    ```
+
+    prints
+
+    ```
+    [          (1.00, 2.00)]
