If that's what Valhalla is working on, then this would be just great. Performance concerns regarding wrappers
are also valid , but here I am talking about implementation complexity.<div><br></div><div>If going little off topic, compiling many classes to achieve generic reification in fact looks odd, but it in fact provides best developer experience, Converting primitive arrays to collections is one of the examples of major problems issues with it, along with some methods of Arrays class (like sort, if I am not mistaken), just don't work with primitives.Approach that is used in C#, while has its downsides, provides much better user experience. However, what I am looking into right now is some hybrid form of generic handling, where generic maybe be reified on demand of developer (or implicitly if primitive is used).
