You're misinterpreting this:

You're print the address of `f` and `n` on the stack, not the 
reference they're pointing to.

But it's true that enums of mutable _arrays_ do create a new 
instance every time they're used:

    enum X {
        A = [1,2,3],
        B = [4,5,6],
    }

    void main() {
        import std.stdio;
        writeln(X.A.ptr);
        writeln(X.A.ptr);
    }

# output:
7FD887F0E000
7FD887F0E010

Whoops, you're right. I forgot you have to cast to a pointer for 
classes.
