What are the cases when one is True, while another is False?

>>> from sympy import Indexed, IndexedBase, Idx, symbols
>>> i, j = symbols('i j', cls=Idx)
>>> Aij = Indexed('A', i, j)
>>> Aij.is_symbol
True
>>> Aij.is_Symbol
False
>>> i, j = symbols('i j', cls=Idx)
>>> Aij = Indexed('A', i, j)
>>> Aij.is_symbol
True
>>> Aij.is_Symbol
False
Aij is not a Symbol but it can be used like one in many cases.
