in reply to Re^2: sv_derived_from gives a confsing result
in thread sv_derived_from gives a confsing result

Seems to be related to the fact that there was no new() method

Sounds feasible. The method doesn't need to be called "new" (with C, at least), but if sv_isobject(sv) is to return true, then the reference (sv) does need to have been blessed into some package ... which is what "new" normally does, of course.
