Re: selectively running unittest functions

[Dicebot]

This will work starting with 2.064:

module a;
import std.stdio;

struct ID
{
    string data;
}

@ID("one")
unittest
{
    writeln("1");
}

@ID("two")
unittest
{
    writeln("2");
}

void main()
{
    import std.typetuple;
    alias tests = TypeTuple!( __traits(getUnitTests, a) );

    foreach (test; tests)
    {
        foreach (uda; __traits(getAttributes, test))
        {
            static if (is(typeof(uda) == ID))
            {
                if (uda == ID("two"))
                    test();
            }
        }
    }
}

It will print stuff twice though because I didn't suppress native 
unittest runner. Didn't actually dwell deep into runtime hooks so 
don't know what is best way to do it (maybe we need one more 
enhancement for it)
