Hi Adrian,

The reason for existence of lang/ and of pology/lang/ is that the latter
is a part of the Pology Python library, and the former a part of the
Pology utilities. On installation, the latter goes into
$PREFIX/python/lib/python.../dist-packages/ and the former into
$PREFIX/share/pology/. The former should also at some time in the future
be able to be supplanted by data in $HOME/.local/share/pology/.
So please revert this change.

In general, I think it is best to stay away from any refactoring
in the process of porting to Python 3. And do that only after porting
is reasonably complete.
