Comment #25 on issue 821 by asmeurer: multiple arguments for max and other
improvements
http://code.google.com/p/sympy/issues/detail?id=821
Sure, feel free to set the milestone. Those are half superficial anyway
since they just get postponed if no one has time to work on the issue :)
As to complex numbers, there are multiple ways to "compare" them, none of
which are actual comparison in the sense of what Max is doing, so I think
we should just not allow them.
On the other hand, pragmatically, it can be a pain to assure that
everything is explicitly assumed to be real, so maybe it should just assume
it is real unless it is explicitly otherwise (e.g., a symbol is complex by
default, but Max(x, 1) will assume it is real; on the other hand Max(1, I)
will not work because I cannot be real).
I think this is already in some ways the standard for the inequalities, and
probably should become that way (unless others have other thoughts).
