           Summary: static if as final statement with no code causes
                    containing code to be skipped

Hard to describe.

---------------------
void foo()
{
        Stdout.formatln("I'm transient.");

        static if(true)
        {
                // Comment me.
                Stdout.formatln("true.");
        }
        else
        {
        }
}

void main(char[][] args)
{
        foo();
}
---------------------

This code prints

I'm transient.
true.

As expected.

Comment the "comment me" line, however, and the "I'm transient" is never
printed.

Alternatively, change the "static if(true)" to "static if(false)" and the same
thing happens since the 'else' is empty.

Ways to make it go away:
- Have at least one statement in the static if clause that is selected.  Even a
no-op statement such as "int x = void;".
- Have more than one statement before the static if.
- Have at least one statement after the static if.

I'm really kind of flabbergasted.
