[Distutils] py_modules AND packages?

[Thomas Heller]

Why is it not allowed to install py_modules AND packages
in the same setup-script?

I have a distribution where an extensions is installed
in c:\python22\lib\site-packages\<ext.pyd>, and a package is installed
in c:\python22\lib\site-packages\<packagename>.
No problem so far.

I want to hide the extension in a Python module, so that
I can implement additional functionality in this module in
Python, and convert it to C and move it into the extension
later.

Currently, this is not possible: 
  error: build_py: supplying both 'packages' and 'py_modules' options is not allowed

A tiny patch to build_py makes it possible (at the end of this mail),
also it would be easy to write a custom build_py command which allows this.

Would there be any harm, or is it simply that Greg did not think
of this?
