+Interoperability with str-only interfaces
+-----------------------------------------
+
+For interoperability with interfaces that only accept strings, interpolation
+templates can be prerendered with ``str``, rather than delegating the rendering

+the default rendering, without any convenient way to decide to do something
+different.
