My base problem is that I want to mixin `break` into a switch statement, but the mixin is within a static foreach. Take a look at the following code:

    switch(foo)
    {
        static foreach(f; EnumMembers!Foo)
        {
            mixin(format("
                case Foo.%s:    bar = Bar.%s;    break;
            ", f, f));
        }

        default: /* do stuff */; break;
    }

The above code returns the error "Error: must use labeled `break` within `static foreach`". For a more complete example, take a look att this sample code: https://dpaste.dzfl.pl/f3ab6d9679fc

I also attempted this solution, but I got the error that the label didn't exist. (And it looks pretty ugly)

    mixin(format("%s: case Foo.%s: abc = Foo.X%s; break %s;", f, f, f, f));

Any of you have a solution for this problem?

Best regards,

Put the label on the switch

whatever: switch(foo)

then use the label here

break whatever;

Would labelling help?
