the header of const AuString & is the same as std::string_view therefore nothing changes. in fact, we still need to alloc strings a bunch of times for a zero terminated string. worse, <c++20 always allocs each time we want to access a hashmap with o(1) lookup, making small hashmaps kinda pointless when we always have to alloc+copy (thx std)

perhaps this will help some language binders
