Ought I to be fired for writing something like this?

#!/usr/bin/env python

def attr_reader(name):
     return '''\
def get_%s(self):
     return self._%s
%s = property(get_%s)
''' % (name, name, name, name)

class Testes:
     _a = 42
     exec attr_reader('a')

t = Testes()
print t.a

Output: 42
