Compilation of this code:

import std.stdio;

void main() { }

class c {
        this() {
                enum string b(alias d)() {
                        return `writeln("a");`;
                }

                int a;

                {
                        mixin b!a;
                        mixin b!a;
                }
        }
}

fails with dmd v2.078.1 and error

However, code:


import std.stdio;

void main() { }

class c {
        this() {
                enum string b(alias d)() {
                        return `writeln("a");`;
                }

                int a;

                //{
                        mixin b!a;
                        mixin b!a;
                //}
        }
}

compiles successfully
