How can you speed it? Does anyone know if pytable can take

    >>> 
    >>> class Student:
    ... 	def __init__(self, name, age):
    ... 		self.name = name
    ... 		self.age = age
    ... 
    >>> 
    >>> students = [Student('John', 18), Student('Jill', 17)]
    >>> students.sort(lambda x,y: cmp(x.age, y.age))
    >>> [student.name for student in students]
    ['Jill', 'John']
    >>> 

See `help(list.sort)` for details.
