The C++ interface is intentionally minimal: it provides only a couple of niceties in order to largely stay out of the way. It is mostly used to provide: * RAII for opaque resources * Safe up and down casting for nodes * string_view for various resources * Iteration over resource lists Note that if consumers want to use it, they must be on C++17 at minimum. https://github.com/ruby/prism/commit/57b8dbe0e9
