Hi Neal,

Could you please be a be a bit more specific? In particular, could you provide an example of something that this proposal precludes but the for-each construct (which is already in the language) does not? Once we have such an example, we'll be able to weigh the pros and cons intelligently.

Thanks,

Josh

Josh-

This approach precludes some designs for reifying generics in the future because it is defined by the implicit creation of non-reified interfaces (e.g. List, etc). It isn't clear if we'll ever add reification, but it would be a shame to restrict or remove our option to do so. You can avoid this by not implicitly tying language constructs to particular existing interfaces. Regards, Neal
