Hy

We finally took the time to implement gensym, as well as a few
other bits that help macro writing. Check the changelog for
what exactly was added.

The biggest feature, Reader Macros, landed later
in the cycle, but were big enough to warrant a release on its
own. A huge thanks goes to Foxboron for implementing them
and a massive hug goes out to olasd for providing ongoing
reviews during the development.

Welcome to the new Hy contributors, Henrique Carvalho Alves,
Kevin Zita and Kenan Bölükbaşı. Thanks for your work so far,
folks!

Hope y'all enjoy the finest that 2013 has to offer, - Hy Society
