Sorry, I'm rather ignorant when it comes to this, but why can't we use [pegged](https://github.com/PhilippeSigaud/Pegged) to transpile C++ code to D?

Mixing semantic with parsing isn't necessarily a good idea.
Then we won't need a nogc compatible std library and so many other things could get easier, like getting legacy code to use Dlang.
That doesn't solve the ABI compatibility to C++, only if source is available, but they may be compiled with compilers which can't build anymore with the current tool chain at least without to rebuild the tool chain.
It might not be worth it for C+17 and beyond, but older codebases could benefit significantly, right?
The problem is that old looking code doesn't become modern when it is transpired to D as the concepts to do things have changed.
