Well, I think the type system can be extended to manage that: the programmer may specify an optional compiler command line argument like: -ms 128 Now all structs/static arrays more than 128 bytes long are passed by reference :-) Alternative solution, less extreme: instead of changing the value/ref pass semantics, when you add such optional command line argument the compiler gives you a compilation warning (or even error, if you want) everywhere you try to pass by value struct or static array more than 128 bytes long.
