Python lacks a mechanism to add user-defined operators. (R has this

That would be neat. But remember, you would have to define the operator
precedence as well. So you could no longer use a recursive-descent parser.
That wouldn't be a problem provided the new operator symbol and its
precedence is known at a compile time, and defined before use.
