Cppfront : A new syntax for C++

[Tejas]

https://github.com/hsutter/cppfront

People working towards syntax improvements as well to C++ now, 
which they believe will pave the way for semantic improvements 
that break backwards compatibility with C++

Taken from the repo:

> **Important disclaimer**: This isn't about 'just a pretty 
> syntax,' it's about fixing semantics. The unambiguous 
> alternative syntax is just a means to an end, a gateway that 
> lets us access a new open space beyond it — and sure, if we 
> build a gate, then the gate ought to look nice too, so we build 
> it with good boards and paint it nice colors. But the gate is 
> the doorway, the portal, not the goal... the real payoff is 
> gaining access to that new open space in C++ that's free of 
> backward source compatibility constraints where we can 
> (finally) fix semantics — order-independence, great defaults, 
> regular composable semantic meanings — as we see fit.
