Ah, simple solution to unittests inside templates

[Andrei Alexandrescu via Digitalmars-d]

Recall the discussion a few days ago about unittests inside templates 
being instantiated with the template. Often that's desirable, but 
sometimes not - for example when you want to generate nice ddoc 
unittests and avoid bloating. For those cases, here's a simple solution 
that I don't think has been mentioned:

/** Awesome struct */
struct Awesome(T)
{
    /** Awesome function. */
    void awesome() {}
    ///
    static if (is(T == int)) unittest
    {
        Awesome awesome;
        awesome.awesome;
    }
}

The unittest documentation is nicely generated. The unittest code itself 
is only generated for one instantiation.
