Since modshim isn't money patching and appears to only be wrapping the external API of a package, if the change is deep enough inside the package, wouldn't you end up reimplementing most of the package from the outside?
There are a couple of example of this readme: (1) modifing the TextWrapper object but then use it through the textwrap library's wrap() function, and (2) modifing the requests Session object, but then just using the standard requests.get(). Without modshim (using standard monkey-patching) you would have to re-implement the wrap and get methods in order to bind the new TextWrapper / Session classes.
- what's the performance like for big packages (say, pytorch)? Have you done some benchmarking?
- is typing kept for the shims? My immediate guess, again, without even trying it out, is not. If yes, how?
