+Title of the Design
+===================
+
+<!-- Describe your change here.  This is purposefully freeform: we want
+enough information to evaluate the design, but not so much that you're
+annoyed by the overall design process and decide to bake cookies instead.
+-->
+
+## Example
+
+<!-- Specify an example of how the user would use this.  It helps other
+contributors get a feel for how this will look in real code, and provides
+a good opportunity to evaluate the end-user feel of the code for yourself.
+
+If you find yourself groaning at verbosity, copy-and-pasting a lot, or
+writing a bunch of tiny helper functions, it's a good indication that you
+might need to re-evaluate the user experience of your design.
+
+This is also a good opportunity to stop and write a proof-of-concept, if
+you haven't already, which should help catch practical nits with the
+design. -->
