Small edit: you can remove the "CallerRet" alias by doing the 
following:

mixin template magic()
{
    typeof(return) magic()
    {
        return typeof(return).init;
    }
}


Though I wouldn't really recommend it as it's very confusing, 
IMO. This works because "typeof(return)" in the return position 
here refers to the caller's scope, while "typeof(return)" inside 
the function refer's to the function's scope.
