Indeed, there are several more -- this will find them, but also
produce some noise:
sage: search_src("return",
I'd like to discuss whether limiting the size of exponents of
variables in Sage is a good way to go, and whether it is necessary to
report an error when breaking those limits. In the default polynomial
ring using Singular, Sage currently reports an exponent overflow error
when presented with a var

Here is a talk I gave that was about many of the many features Magma
has that Sage doesn't have:

Below I'll make a few remarks just because they occurred to me. I'm

the way most programming language grammars work, those based on so-
called context-free grammars, it is important to avoid ambiguity, and
to have constructions that can be parsed regardless of context.
thus
x+y means the same as
(x)+y in most programming languages.

allowing (a,b,c) to be a list of 3 items means that
(x+y) could either be a list of one item, namely x+y
or the expression x+y itself.
So it is probably a bad idea unless you think that singleton lists are
the same as their first element.
And I suspect that you don't want to think that.

I think it means that if the source file is a link, it will copy the link and

I still don't understand exactly what that means, but I get the
general gist, and agree it is not relevant here.
So I think I can give this change a positive review as -p is certainly
not *less* standard than -a.
I have a trac account. I'll change it to positive review.

Dear Sage-Devel,
I found a situation when calling GF(2) returned the tuple
(TypeError, "error coercing to finite field")
I guess the error should be raised and not returned. Or is this
intended behaviour?

error is not raised
