Thanks for trying that out, and you're right, that is weird!

Unfortunately the workaround only seems to work at namespace scope, I've
tried every which way I can think of to get it working inside template
classes (which is where is_convertible will be used after all), all to no
avail.  So although it fixes the test program, it really just masks the
issue, and doesn't (as far as I can tell) help end users.
