One small comment:

"Escaped"? How are they escaped? (with '\'?) If so, how are backslashes
escaped (with '\\'?) And does the mechanism un-escape these for you
before passing them to __format__?


Later...

This violates the specification given above... it has non-escaped '}'
characters. Make up one rule and be consistant.
