There is a lot less code to test and maintain if have one way to provide the input. Add wants items and you can give them as Add(a, b) or Add(*[a, b]) or Add(*list(generator)) -- you let the user maintain their own code/preferences. If you want to allow Add(a, b) or Add([a, b]) or Add(generator) then your overhead at the beginning of the routine gets bloated. And that slows things down. -- You received this message because you are subscribed to the Google Groups "sympy" group. To post to this group, send email to sy...@googlegroups.com.
