Comment (by mmezzarobba):
Replying to [comment:22 migeruhito]:
> I performed my tests with maple 11. Prior to Maple 12, the only sort
option available is session dependent, and I think `--setsort` option is
not available at all. By including it, we will probably break the
interface for older versions of maple. In the other hand, `--setsort=1`
seems to be deterministic for these examples as mmezzarobba said, but it
is the default from version 12. `sort()` is not necessary in this case.
Yes, I forgot that `setsort=1` was in fact the default. However, while
''sets'' are sorted by default under recent versions of Maple, it looks
like expressions aren't. For example, with Maple 17, I get:
{{{
$ maple -t
#-->sin(x^2)+y^z;
sin(x^2)+y^z
#-->{sin(x^2),y^z};
{y^z, sin(x^2)}
#-->sort(%%);
y^z+sin(x^2)
}}}
So I would say that adding the command-line option is indeed not
necessary, but we do need to call `sort()` to make the tests deterministic
under Maple 12+.

Same for me.
