New issue 2639 by asmeurer: Product() should be unevaluated
http://code.google.com/p/sympy/issues/detail?id=2639
Unlike other unevaluated operators, Product() is not always unevaluated.
Attempted evaluation should be the job of product(). This is how
Sum/summation works:
In [2]: Product(n, (n, 1, 2))
Out[2]: 2
In [3]: Sum(n, (n, 1, 2))
Out[3]:
2
__
\ `
) n
/_,
n = 1
In [4]: product(n, (n, 1, 2))
Out[4]: 2
In [5]: summation(n, (n, 1, 2))
Out[5]: 3
