Comment #2 on issue 3642 by [email protected]: rename __name__ string for singletons
http://code.google.com/p/sympy/issues/detail?id=3642

I am working on structural matching and making a list of the object classes. Rather than get this

fp(x+1, string=False)
[<class 'sympy.core.add.Add'>, [[<class 'sympy.core.numbers.One'>, []], [<class
'sympy.core.symbol.Symbol'>, []]]]

I would like to see this

fp(x+1)
['Add', [['One', []], ['Symbol', []]]]

(I know I could create a class and control the printing, but I just wanted to be able to get the class back from the string; "Add" and "Symbol" return back to the classes as I showed in the OP, but "One" does not -- but would if it were "S.One" or if sympify where patched in some way so that singletons are recognized just like Add and Symbol are.)
