C++ Trigger Framework

I'm interested in creating a Postgres extension that would enable developers to write triggers in (modern) C++. Does anyone know if there is already some sort of translation wrapper between the native Postgres C API's and C++? Or if there's already a project that allows for writing triggers in C++ with ease?

I see that https://github.com/clkao/plv8js-clkao/blob/master/plv8_type.cc does implement an abstraction of sorts, but it's specific to v8 types and is not genericized as a way of interacting with Postgres C API's from C++ from any C++ code.

Can you imagine any potential technical challenges I may encounter (e.g. massaging postgres' custom allocator to work with C++'s new and delete operators, or unresolvable compiler incompatibilities)? 

Thanks for any input :-)
