SymPy already has a pretty widely used single dispatch system (the _eval_* methods). Multiple dispatch would be useful for any operation that has more than one argument. I hardly have to convince you of the advantage of this approach.
The challenge is operations like Add and Mul that take an arbitrary number of arguments. How can we reasonably dispatch the logic in Mul.flatten so that it's not such a mess (and also so that we don't need things like MatrixMul or QMul)? I haven't looked at the upapjojr pull request. My understanding is that it doesn't handle the Mul case, which is the one that most interests me.
