If you relax the enhancement to just noting the line where the debug print came from, it doesn't need to be deep compiler magic - the same kind of stack introspection that warnings and tracebacks use would suffice. (Stack introspection to find the caller's module, filename and line number, linecache to actually retrieve the line if we want to print that).


P.S. While super() is a *little* magic, it isn't *that* magic - it gets converted from "super()" to "super(name_of_first_param, __class__)". And even that limited bit of magic has proven quirky enough to be a recurring source of irritation when it comes to interpreter maintenance.
