I'm not sure about the "auto using" of all variables though; wouldnt it be possible to statically check for the used variables and only import what's needed, for performance reasons? Also, how hard would it be to add type hints (only for parameters)? Sometimes they are needed to make the IDE know the variable type because it can't be guessed automatically. I know about your note in RFC,this is just a question to other internal members.Return type can be infered by IDEs from the simple expresion quite easily. PS: would "() ~> foo()" work? I think it should, but I couldn't find a mention about it in RFC. :) Regards Pavel Kouril
