Comment(by novoselt):
OK, I am fine with the forth patch
(trac_10529_SubschemeMorphisms_without_QuotientRing.patch).
I think it is very bad that the class description states
{{{
A morphism of schemes determined by rational functions that define
what the morphism does on points in the ambient space.
}}}
and yet the previous version was expecting (with `check=False`)
polynomials in the quotient ring and the new one - in the original
polynomial ring. It is also bad that a generic class does something
special for projective targets. But fixing all this is beyond the scope of
the ticket and I think that this patch is an improvement to the current
situation.
