    Norvig's Treatment of the Zebra Puzzle

Here's Peter Norvig's treatment of the zebra puzzle from his CS212 course.

  
## wtf.py
class A(object):
    def hook(self, f):
        atime = 0
        def intime(*args):
            print atime
            atime += 1
            return f(*args)
        return intime

>>> f = A().hook(lambda b: b + 1)

## namedstruct.py
#!/usr/bin/env python
from collections import namedtuple
from struct import Struct


class NamedStruct(Struct):
    def __init__(self, name, fields, byteorder=None):
        fmt = (byteorder or '') + ''.join(field[0] for field in fields)
        super(NamedStruct, self).__init__(fmt)
        self.namedtuple = namedtuple(name, (field[1] for field in fields))

## jam.js
var fs = require('fs'),
  path = require('path'),
  glob = require('glob').glob;

exports = module.exports = function jam(options) {
  options = options || {};
  var patterns = options.patterns || [];
  var root = options.root || path.join(__dirname, 'public');
  var namespace = options.namespace || 'JST';
  var output = options.output || path.join(root, 'jst.js');

## save.py
from contextlib import contextmanager

@contextmanager
def save(obj, attrs=None):
    """Save attributes of an object, then restore them.

    Example:
    import breakfast
    with save(breakfast, ('eggs', 'bacon')):
        breakfast.Eggs = lambda: "Eggs"
