Comment #6 on issue 2406 by asmeurer: improve Tuple constructor
http://code.google.com/p/sympy/issues/detail?id=2406
I don't understand how from_iter would fix the *args problem. Are you
suggesting to change the convention from expr.__class__(*expr.args) to
expr.__class__.from_iter(expr.args)? I'm not sure if I like that.
Why not just make Tuple the equivalent of a tuple literal (1, 2, 3), and
create some function (sympy_tuple or to_Tuple; I can't think of a good name
now) that serves as the equivalent of tuple(). This wouldn't require any
major API changes.
