an inplace_pow function using the C-API, you can only pass one argument to it.
You can see that in the attached screenshot.
The example class shown in the screenshot can be found here

Using the C-API, the inplace_pow numbermethod is always called with the third

New submission from Zuzu_Typ :
It should be considered to increase the refcount of functions that are passed
on to an external library at some point.
If this is not done and e.g. the function was a local variable, when leaving
the scope it gets garbage-collected. When the library now tries to
