I'm not sure I want to hide the file. I don't actually use xxx.sage files
much, but when I do, I usually just delete the py file right away, and if

It may be surprising that the first row of the order matrix is
interpreted as degree

By the way, Volker, this is not fixed by
http://trac.sagemath.org/sage_trac/ticket/11819, since 'new' is imported by
twisted, not just by the Sage library.

This took me by surprise:

I didn't find the docstring helpful on this.

The following creates three variables ``a``, ``b``, and ``c``::

You can of course write T_a=300*units.tempe

In my case, sometimes keeping multiplication coefficients, even in a sparse
form, is less efficient than recomputing them over and over again, from a
set of sparse matrix generators.

It is #11817, and ready for review.
It also fixes a fact in sage.misc.sagedoc.format, that ironically is
responsible for the fact that sage.misc.sagedoc.format? did not show
the docstring.

Hi!
Until today, I thought that introspection via "?" uses sage_getdoc. I
stand corrected. Apparently it just uses _sage_getdoc_unformatted.
While sage_getdoc is supposed to remove the embedding information,
introspection with "?" and _sage_getdoc_unformatted show the embedding
information:
