If you're referring to a specific module and youreally care, just check sys.version. (That's annoying and ugly enoughthat it'd probably make you thing about why you are doing it - Icannot honestly think of a case where I'd actually want to check incode if a module is a preview - hence my question as to what your usecase is).Feels like YAGNI to me.Paul.
