Alternative syntax for C++, a la Genie for Vala?

The Vala language compiler can handle a very different looking syntax, Genie, which argua开发者_JAVA技巧bly could be considered a different language or an alternative syntax for one language. AFIK, anything you can do in Vala, you can write in Genie (ignoring work-in-progress details, bugs) to the delight of anyone who doesn't like curly brackets.

Is there some language or alternative syntax bearing the same relation to standard C++ that Genie has with Vala? It should allow doing anything that one might do in C++. (It need not be readable by the normal C++ compilers, however - I don't expect that at this point in time.)

(Side issue: Genie/Vala is the only example I can think of now. Are there other examples?)
