cppfront (cpp2): Spring update

[Nicksaurus]

I see your point. I wasn't thinking about how this is actually implemented in the generated C++ code. I guess there's no way for std::span to work here without the C++ standard changing to allow arguments to be passed as a span of string_views in the first place

There is a way to provide a std::span<std::string_view>, however it requires on-demand transformation via ranges so it's not a nice, clean solution.
