This looks like a great compromise, allowing developers to utilize the
default implementation for a specific type with very little code.  A
prominent warning against doing so in shared libraries would still be
needed, of course.  I look forward to experimenting with this design
soon!

Thank you very much for the suggestion!  Also, thank you for the
example code, as this pattern is new to me.

Best regards,

Travis
