[GiNaC-list] quo behaviour

Hello, sorry for bothering you so much, you probably think by now I get paid for this. The tutorial says that parameters to quo() should be univariate polynomials. Is this really necessary, esp. if you also get the main variable as parameter? Even if I accept the univariateness for parameters[*], the behaviour of the function towards multivariate input is inconsistent, as the ginsh session shows:

quo(y,y*x,y); FAIL quo(y*x,y,y); x

Thanks, ralf [*] I do not accept it, as I understand ginac from its interface to be inherently multivariate, except for the diff function, and even that is disputable.
