Contribute to flint, which is open source and already used by Sage and
which is working very hard to be better than Fermat at much, if not
all, of what Fermat does.

That doesn't sound good at all.
It's often important to check that it is reporting actual bugs though.
Sometimes it is bash, libc, libstdc++ or some other system code that
is actually the problem. If you build a simple C++ program that really
does nothing except say make a call to the std library

I built a small C++ program that uses linbox to compute the characteristic
polynomial of an integer matrix analogously to what Sage does. When I run it
in valgrind, I get tons of warnings about "Conditional jump or move depends
on uninitialised value(s)". Although potentially ok, I'm feeling som

To make sure you did not misunderstand me: I suggested disabling

Anyway, if the dependencies are explicit this problem doesn't even

I agree that the doctests are rather rigid, but since they are very
useful, I believe we should certainly not abandon doctests.
Hi!
We have
sage: v = vector(ZZ,[1,2])
sage: M = matrix(ZZ,2,2,[1,2,3,4])
sage: cm = sage.structure.element.get_coercion_model()
sage: cm.explain(v.parent(),M.parent(),operator.mul)
Action discovered.
Right action by Full MatrixSpace of 2 by 2 dense matrices over
Integer Ring on Ambient free m
With regard to...
1.) I don't see a problem with that - the only problem might be the
rather rigid concept of doctest itsself. But if the routines return
different values which are still mathematically correct and you can't
make doctest account for it then that's the way it shall be, no? You

It would be nice if one could specify a subset of spkgs to use the

Hi,
I would like something like this to work:
L = line([ some 2d points ])
L.translate(1, -1)
I don't find how to transform a line to a list of points.
But L[0] seens almost right (when L is a line)
You apply the function lambda (x,y):(x+1,y+1) to each point.
So map (lambda(x,y):(x+1,y

I agree that I need to set the attribute Element not element_class in my
path. I'll fix it after the dust in #10496 has settled.
I'm still confused about _element_class(). If you need to compute the
correct value of Element, then just do that in the constructor. So if
_element_class() is only
