Hi Pádraig,

If I remember correctly the three possibilities are effectively severity
levels for an 'out-of-order' exception:

--nocheck-order => SILENT (don't actually check)
--check-order   => FATAL

For me "mismatch" and "unsorted" aren't obvious keywords, but I can see
how an argument to the --check-order option could be clearer than the
current interface.

Would an _optional_ argument using a scheme like the one you suggested
above be worth providing?  I suspect it might actually add to confusion
due to the need for continued support for the current scheme as well,
but it should be possible to allow both:

--nocheck-order => --check-order=none
  [DEFAULT]     => --check-order=warning
--check-order   => --check-order=fatal
