In the past I've suggested that these string prefixes be made user-definable. I was just starting out learning programming for serious back then (which I never really did BTW), as a uni dropout, so that was a bit stupidly audacious of me maybe. But I still think that this is what Python should do. Because the way things are, they keep changing the syntax all the time and they have nothing like Perl's "use v..." syntax, which can cause problems like a script written for python 3.n can fail with a _syntax error_ when run with an interpreter 3.(n-1), and that _is_ a fiasco, compared to an error like "AttributeError: type object 'str' has no attribute '__prefix_f__'". I guess same goes with the "@" operator, this sort of things are what major versions are for.
