## Fishing for references with Guppy |
|
|
|
|
|
|
|
Guppy! |
|
|
|
So, this boils down to finding all of the references to a particular object, |
|
|
|
and then updating them to point to a different object. |
|
|
|
|
|
|
|
## Handling different references |
|
|
|
But how do we track references? Fortunately for us, there is a library called |
|
|
|
[Guppy](http://guppy-pe.sourceforge.net/) that allows us to do this. |

Certainly, not every case is handled above, but it seems to cover the vast |

majority of instances that I've found through testing. Remaining areas to |
|
|
|
explore include behavior when metaclasses and more complex descriptors are |
|
|
|
involved. Implementing a more complete version of `replace()` is left as an |
|
|
|
exercise for the reader. |
