Tuple behaves different for summation of logical

[Duane Nykamp]

Is this intentional behavior?


In [1]: from sympy import Tuple

In [2]: sum( (True, False, False))
Out[2]: 1

In [3]: sum(Tuple(True, False, False))
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-3-602f84e54f9b> in <module>()
----> 1 sum(Tuple(True, False, False))

TypeError: unsupported operand type(s) for +: 'int' and 'BooleanTrue'
