in thread I don't understand UNIVERSAL::DOES()

For those of us who can't just presume that 5.010 <= $], how about making UNIVERSAL::isa() check $_[0]->can("isa") if $_[0] is blessed and deferring to that sub if it isn't UNIVERSAL::isa()? Or do you also need to worry about Some::Class::isa() calling UNIVERSAL::isa() and is there no sane way to work around that even from C? Or is there some other reason that this wouldn't be a good idea?

    I think that it could have backwards compatibility issues that would preclude it from happening in UNIVERSAL::isa(). Which is why ive been harping on about making DOES do the right thing.
