From the blog post: 'I routinely found myself using free-form linguistics as an integral part of longer computations — randomly interspersing Mathematica syntax and free-form linguistics on different lines in a Mathematica session, and just using whichever was most convenient for a particular input. And here's an exciting part: in Mathematica 8 the free-form linguistics doesn't just operate line-by-line. It knows the context in which it's used in a notebook, so you can use it to build things up.'"
