The only thing I can agree on here is performance, but I already included that aspect before. I don't see how existing expression evaluation could be more or less "ergonomic." It is what it is and it's already far better than anything for C/C++. And since classes and functions are all objects in python and there are no private members, everything is trivial to redefine in practice. I do this constantly.
