Version Bump
Ooops, do not use Scalar::Util::isdual

When we do variables change somehow and diagnostics go haywire :-(

Essentially cmp_ok( 4, '==', $string )  seems to turn $string into a
dualvar, but Test::More could not detect it and printed the right thing.
isdual is better at detecting the dual var, so the diagnostics print the
numeric conversion instead of the original string :-(
