Hi,
at
http://trac.sagemath.org/sage_trac/ticket/11764
Paul Zimmermann writes:
"""
for univariate polynomials we have the class Polynomial:
sage: R.<x> = QQ[]
sage: isinstance(x+1, Polynomial)
True
However for multivariate polynomials we have to write:
sage: R.<x,y> = QQ[]
sage: isinstance(x+y, sage.rings.polynomial.multi_polynomial.MPolynomial)
True
I suggest MPolynomial is defined as an alias for
sage.rings.polynomial.multi_polynomial.MPolynomial so that we can
simply write:
sage: R.<x,y> = QQ[]
sage: isinstance(x+y, MPolynomial)
True
"""
I suggested this needs a discussion on [sage-devel] because it's about
adding *more* stuff to the global namespace, while we try to keep that
to a minimum.
Thoughts?
Martin
