I think if we get this right, we might unlock some cool new usages. I really
believe that if we simplify integration of multipl

Hi Terry!
Thanks for your feedback, I have a couple comments below.

Hi folks!
We started a project to extend Python with a full-blown query language about
a year ago. The project is call PythonQL, the links are given below in the
references section. We have implemented what is kind of an alpha version now,
and gained some experience and insights about why and
make nested queries easier to write and a few minor bells and
whistles.

Hi Folks,
We have released PythonQL, a query language extension to Python (we have
extended Python’s comprehensions with a full-fledged query language,
drawing from the useful features of SQL, XQuery and JSONiq). Take a look at the
project here: http://www.pythonql.org and lets us know what yo
