While this may be true for Python, it is certainly not true for Tcl.
Tcl has a very clearly defined API for internals and you cannot bypass
this API from extensions.  They have kept this API constant for the
whole Tcl 8.x release series, and as a consequence all extensions are
completely binary forward and backward compatible along all releases.

While I don't care too much for the Tcl language itself, I've been
envious of their clean internal abstractions for quite a while now.
