Hey All,

I'd like to announce the release of MacroPy 0.1.7 (
https://github.com/lihaoyi/macropy). MacroPy is an implementation of
Syntactic Macros in the Python Programming Language, which we used to
implement a pretty impressive list of demo macros:

   - Case Classes <https://github.com/lihaoyi/macropy#case-classes>, easy
   Algebraic Data Types from Scala
   - Pattern Matching
<https://github.com/lihaoyi/macropy#pattern-matching> from
   the Functional Programming world
   - Tail-call Optimization<https://github.com/lihaoyi/macropy#tail-call-optimization>
   - String Interpolation<https://github.com/lihaoyi/macropy#string-interpolation>,
   a common feature, and
Pyxl<https://github.com/lihaoyi/macropy#pyxl-integration>,
   which is basically XML interpolation.
   - Tracing <https://github.com/lihaoyi/macropy#tracing> and Smart
Asserts<https://github.com/lihaoyi/macropy#smart-asserts>,
   from every programmer's wildest dreams.
   - PINQ to SQLAlchemy<https://github.com/lihaoyi/macropy#pinq-to-sqlalchemy>,
   a clone of LINQ to SQL from C#
   - Quick Lambdas <https://github.com/lihaoyi/macropy#quick-lambdas> from
   Scala and Groovy
   - Parser Combinators<https://github.com/lihaoyi/macropy#parser-combinators>,
   inspired by Scala's
   - JS Snippets <https://github.com/lihaoyi/macropy#js-snippets>, cross
   compiling snippets of Python into equivalent Javascript

Along with a really nice readme which serves both as a demonstration of the
capabilities of macros <https://github.com/lihaoyi/macropy#macropy>, and
also as an introduction to the macro-writing
process<https://github.com/lihaoyi/macropy#detailed-guide>
.

This is probably going to be the last release that bundles all these demos
together; future releases will begin properly breaking up the various
macros into their own projects, and nicely polishing the core
infrastructure into a solid foundation for others to build upon.

We think that this is a pretty cool project, and can serve as a easy way
for people to prototype modifications to the python language. We're looking
forward to your feedback and welcome contributions =)
