--- Comment #3 from Giuseppe D'Angelo <dangelog at gmail dot com> --- Hello Patrick, Thank you for the insights. I'm left wondering however if the CWG resolution would possibly ever allow the operator== to be defined as a hidden friend; the workaround you mentioned may lead to redefinition errors (as now it doesn't depend on S any more)?
