I will add this to the wiki later. My only issue with option 3 is when dealing with objects that need both an id/name/handle and some sympifiable information (like unspecified number of dimensions). The MatrixSymbol is good example.
One way around this is to implement BasicString but this will end in reimplementing a badly defined type system instead of using the one provided by python. Or we can say that Symbol is our string type (which some time ago Aaron was in favor of, but Ronan was agains). Somewhat related, why should we use Integer(1) and not int(1)? -- You received this message because you are subscribed to the Google Groups "sympy" group.
