def some_anonymous_function(arg1, arg2):
   print "%s %s" % (arg1, arg2)

def some_named_function(func, arg1, arg2):
   func(arg1, arg2)

some_named_function(some_anonymous_function, arg1, arg2)

def fn(body):
    exec "def a_function" + body
    return a_function

fn("""(x):
    print x
    return x + 1""")(2)

Classy.
