It seems cleaner if we could just share say utf8::VERSION.  SWASHNEW
seems likely to be changed as it "feels" more like a implementation
detail.  But if thats what utf8 checks... well then thats what it
checks.

It seems safer if there was some way to 'opt' in say if utf8 was
loaded then make safe do the above.  Or maybe a pragma? use utf8
qw(utf8);   We would still have to patch postgres...  But I can
imagine there are some users of utf8 that dont want utf8 strings.  BTW
as I could not reproduce this does this mean that reval->('"\x{}...")
works while reval->('sub { "\x{}"}') does not ?  Or is it before the
first one failed while the closure based one worked?
