If that's what you want, then you can directly instantiate My_Validate_Regex
and pass its instance to addValidator().
But anyway, IMHO, it's better to pass 'Regex' and let the plugin loader
figure it out as this way when you need to override the Regex validator, you
just configure the validators path prefix and everything works.
