I love it. If this could transparently convert to and from normal Python I could see wrapping it in an editor plugin so that the braces could be visible to those of us who prefer them, while the output could remain traditional Python for interoperability with an established codebase.
It would be simpler to just make an editor which displays a { after any end-of-line colon and lines with } before each deindent, without actually adding them to the file.
