Resume
Einfall is, roughly, the German word for ‘insight’, or ‘bright idea’, which she discovered while reading the wonderful book ‘How to Solve It”, by Polya. It’s worth owning a copy.

I like Amory Lovins’s description of Einfall: “temporary lapses of stupidity”. I second the Polya recommendation
by Fortress, do you mean http://research.sun.com/projects/plrg/ ?!
its barely even a stable language implementation!
It’s not stable enough to build on substantially yet (we’re awaiting static steps for the compiler,) but it’s an excellent language. I’m involved in a semi-secret project to produce an interactive environment with Fortress as a base. Right now I’m using Mathematica as my native language.
