Had a fun discussion/twelf hacking session with lambdacalculus. It was like watching an action movie with constant and harrowing dangers at every turn but ultimately a happy ending. Except that giving the hero suggestions actually resulted in a greater chance of success. And the hero was a program. A program that is an implementation of a dependent type theory. Which, I admit, is not the typical setup of your average hollywood summer-blockbuster explosion-fest. But I would so watch that movie.
