New issue 2082 by andy.terrel: No SymPy class 'Composition'
http://code.google.com/p/sympy/issues/detail?id=2082
Composition seems to have been removed but operations still thinks its
there.
/Users/aterrel/workspace/sympy/sympy/core/operations.pyc in identity(cls)
73 if cls is Mul: return S.One
74 if cls is Add: return S.Zero
---> 75 if cls is C.Composition:
76 from symbol import Symbol
77 s = Symbol('x',dummy=True)
/Users/aterrel/workspace/sympy/sympy/core/core.pyc in __getattr__(self,
name)
246 cls = BasicMeta.classnamespace[name]
247 except KeyError:
--> 248 raise AttributeError("No SymPy class '%s'" % name)
249
250 setattr(self, name, cls)
AttributeError: No SymPy class 'Composition'
