Hi. What function signature should I use for receiving a
constant
reference of an r/l value object? Is it auto fn(inout ref const
myClass obj)?
I want to:
1. Take a constant reference of the object, not copy them
2. The object itself may be const or non const.
ref const(Type) would be the const version of ref Type. e.g.
auto foo(ref const(int) i) {...}

Thanks. Just a couple of follow-ups:
1. I've never seen a signature like `const(int)`is the enclosing
parenthesis around the `int` necessary?
2. What effects does prefixing the arguments with `inout` have?
For example: fn(inout ref const string str){...}
