"Also itll be interesting to see how they deal with pointers, particularly function pointers and accessing the stack, the sort of low level details other sandboxed languages dont have"
For a useful real world example you can see the implementation of EOS blockchain (https://github.com/EOSIO/eos). The blockchain has a webassembly virtual machine in which the smart contracts run. The smart contracts are written in standard C++17. The compiler is clang 7 that targets wasm (see the SDK: https://github.com/EOSIO/eosio.cdt).
