Don't use string == null, it is true for empty strings since null

You can try if(string is null) - is instead of ==. Though usually
in D, I just if(string.length == 0) and treat empty and null the
same way.

But with the current D front-end it's not a good idea to generate

I think this is not good advice. Comparing string to null is perfectly
fine with ==. It's fine *because* null and empty strings are the same

It seems that you can not do so because writeln() something back,
which leads to RUNTIME_ERROR in DMD
I quite often have to write similar designs:
