Hi,

I am developing one object called py4pd to allow me to load some Python 
functions as objects (very similar to py/pyext). I have one problem with 
class_setsavefn, because I need something similar to #X declare -lib mylibrary 
(an extra line in a specific place in the PureData Patch file) to load the 
Python functions before pd tries to load the Python objects that are added by 
the Python module (called pd).


``` py

import pd


def mygreatfunction(x, y)

 somegreatthing(x, y)


def py4pdLoadObjects():

    pd.addobject(mygreatfunction, "py.greatfunction")


```


To do that, I am working with this function 
link<https://github.com/charlesneimog/py4pd/blob/a49dd8b1c28e3162a45a805781f7cac31197c347/src/py4pd.c#L1641>.
 It works in some cases, but I have problems with undo and redo and a lot of 
instabilities with specific actions.

Question:

      Someone already had to add some extra lines in the pd patch in some 
specific order?

      What is the right way to do it?


One observation:
      I am adding one new canvas_class method called py4pdLibrary, it loads the 
Python Library (the objects).


Thank you very much!
