I found another technique that may be more robust to `namedtuple` being
accessible under different names. We can replace `namedtuple`'s code object at
runtime in order to interpose on calls to it:
```python
import types
def copy_func(f, name=None): # See
http://stackoverflow.com/a/6528148/590203
return types.FunctionType(f.func_code, f.func_globals, name or
f.func_name,
f.func_defaults, f.func_closure)
from collections import namedtuple
namedtuple._old_namedtuple = copy_func(namedtuple)
def wrapped(*args, **kwargs):
print "Called the wrapped function!"
return namedtuple._old_namedtuple(*args, **kwargs)
namedtuple.func_code = wrapped.func_code
print namedtuple("Person", "name age")
```
This prints
```
Called the wrapped function!
<class 'collections.Person'>
```
