Hi!

While rebuilding the python related packages against the Python 3.15rc2 version we found that python-kaptan fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4856779/

From the log, the error seems to be:

if sys.version_info[0] == 3 and sys.version_info[1] > 2: # Python >= 3.3
              import importlib.machinery
loader = importlib.machinery.SourceFileLoader('', pathname)
  >           mod = loader.load_module(mod_name)
                    ^^^^^^^^^^^^^^^^^^
E AttributeError: 'SourceFileLoader' object has no attribute 'load_module'. Did you mean '.exec_module' instead of '.load_module'?

This is because load_module is no longer supported. From https://docs.python.org/3.15/whatsnew/3.15.html:

The load_module() methods of Loader and its subclasses is removed. The import system will no longer call it when defined on custom subclasses. The method has been deprecated in favor of exec_module() since Python 3.4. (Contributed by Brett Cannon in gh-97850.)

Setting the severity to important for now. Once Python 3.15 is released and later added to python3-defaults, this bug will become release critical.
