{
    member = "printThis",
}

void main()

    writeln(member);
}

dmd -run bug

----
Output is 'member' instead of 'printThis'.

At best this is an enhancement request. But you are asking to add to make a special case for string enums.
Comment 2 Peter Alexander 2014-01-27 12:41:31 UTC 
I think this is by design.

The EnumBaseType just indicates that the enum values can be implicitly converted to the EnumBaseType. It's not the same as `enum string member = "printThis";`

I'm not a fan of special casing the output of string enums.
Comment 3 Martin Nowak 2014-01-27 14:23:35 UTC 
Maybe I was too fast with this, I just expected a different result.

With anonymous enums it works btw.

enum name1 = "printThis";
enum
{
    name2 = "foo",
    name3 = "bar",
}

void main()
{
    import std.stdio : writeln;
    writeln(name1, name2, name3);
}
