If we're now making a convention for the global sum function (i.e., try

have a .sum() method? Will this break things?
If you type "sum??" and read yo

Actually, there is also a slight (but sometimes significant)
functional difference between the two methods:

Hi,
This thread is about sum.

This is a very, very misinformed comment. I want to address it,
especially the statement "It's certainly a code bloat." It is
absolutely *NOT* code bloat to define a sum method for

I'm not sure I agree with this. I would expect the global sum() to
try to use a sum method first, and only do the default if that did not
exist, since some classes might have better ways of summing themselves
than the default. But then the only reason for having sum methods
would be if there was
There could be code in other parts of devel/sage/sage that depends
upon .sum(), althouh not too likely.
You should run "make testlong" to see if anything breaks (well, it
takes a while of course )
And then, you know, open a trac ticket with your patch.

I just tried that, it worked
I don't think sum() method is needed. It's certainly a code bloat.
Could you check that sum() in vector_double_dense can be removed?
(remove it there, do sage -b, run testsuite, see if there were any
errors caused by it)
