documentable unittest

[Andrei Alexandrescu]

I'm very happy that this will be part of the upcoming release: 
https://github.com/D-Programming-Language/dmd/pull/1342 (see also 
http://d.puremagic.com/issues/show_bug.cgi?id=2630) allows defining 
unittests that simultaneously work as documentation. This is a great way 
to simultaneously write meaningful tests and good documentation examples.

If you want to help, feel free to hop on the Phobos documentation and 
convert some of it to use the new feature.


Thanks,

Andrei
