However, I feel like the documentation for interfacing with C++ code does not mention the capabilities of the core.stdcpp module and lacks examples of how to use it. I understand that writing documentation takes time, and you guys are busy, but if there is a to-do list somewhere, please consider adding "update docs interfacing with C++" to it.

It seems you already have a good knowledge of what inside this 
module. Probably you can create a PR with some details. And maybe 
someone else will join you in documentation update.
