Hi,

Jut to reiterate what I wrote on IRC:

Please do not write or advocate for import hooks, especially not for porting purposes. It would either mean that people start adding that hook on their own to the code (and that awfully reminds me of the days of 'require "rubygems"' in the Ruby world) or that the init.py has to do that and that's a non trivial thing.

The hook on install time works perfectly fine and the only situation where it might not work is when you're trying to use Python 3.2 for development and also support down to 2.x by using the newly introduced u-prefixes. In this case I would recommend using Python 3.3 for development and running the testsuite periodically from Python 3.2 after installating the library (into a virtualenv for instance).

The current work in progress install time hook can be found here: https://github.com/mitsuhiko/unicode-literals-pep/tree/master/install-hook

Regards, Armin
