Hi there, the patch at
http://trac.sagemath.org/sage_trac/ticket/5576 changes the behaviour of the subs() function for mq.MPolynomialSystem. Instead of modifying self it now returns a new mq.MPolynomialSystem. This matches the behaviour of other subs() functions and not doing it was a stupid design decision due to me. However, this introduces interesting problems. For instance, -long would run out of RAM (fixed in the latest version of the patch) because I forgot to replace a line F.subs(s) with F = F.subs(s). Bottomline: The calling convention didn't change but the behaviour of the function changed. How do we do this properly? We can't just deprecate it. I guess not too many people use that class anyway but still, should we have some protocol for handling this?
