Shallow vs deep ownership

[cpetig]

For passing as a reference std::vector<std::string> const&and std::vector<std::string_view> const& (and less so std::vector<std::string_view>) make sense.

Which one to choose? I tend towards the first.

This gets more prominent with resources!

But std::vector<std::string_view> is your only option if you don't have a vector already containing the objects.

this is exactly the purpose of the --ownership parameter for Rust
