It saddens me, that one of Pythons strengths - its C extensions - appear as a weakness in this context. The culprit is, that we perceive python as 'what you can DO through python' - which is a very reasonable perspective. But precisely python's useful boosting through C extensions, also anchors it to its friends. So, it's the old conundrum of what goes into a language core, versus what api library environment it lives in.
