Piglet – A simple scripting language for data processing inspired by Apache Pig

I'm engaged in monthly projects, of which Piglet was the second of this year. I'm a big fan of Apache Pig, and wondered what a "small-data" version of Apache Pig would look like in code (though it's not a complete version of Pig).

This was implemented very quickly and is not ideal in some cases (RPN for expressions, for example). It's heavily assert-ridden to help in debugging and is not for the faint of heart. But you can see numerous examples to illustrate how it's used.

I'm curious what people think?

Thanks,

Tim.
