Yeah. Jason, I seem to have code that user-provides a copy constructor
(seemingly for no particular reason),
doesn't bother declaring a copy assignment operator, and still breaks
magnificently. :) There is no bug
in it; the assignment works as expected, so that's a false positive. I
am going to suggest taking this warning
out of -Wextra and making it completely separate for GCC 9.
