os.walk is an awesome generator.
However, I needed the same functionality,
only I wanted to walk 'up' the
directory tree.

This allows seaching for files
in directories directly above

From Geoff Anders, of Leverage Research (http://www.leverageresearch.org/)

For people doing goal factoring - or for people making any sort of box-and-arrow diagram - I recommended the program yEd. It is available here: http://www.yworks.com/en/products_yed_about.html

After you install it, I highly recommend setting up the defaults in the following way:

1. Open yEd.
2. Create a new document.
3. Click the white background; a small yellow square should appear on the canvas.
4. Click the small yellow square so as to select it.

Löb with error handling

löb is a well-known function in Haskell for implementing spreadsheet-like behaviors and tying the knot. It is defined as:

loeb :: Functor f => f (f a -> a) -> f a
loeb fs = xs
  where xs = fmap ($ xs) fs
