Hi,
I also think this could be a good thing to have a C4::Normalize. (Maybe
not for 3.0)
Maybe we could broaden the scope.
UTF8 Normalize,
Normalizing publication dates and acquisition dates, and prices, and
maybe even itemcallnumber could also enter this module.

I am not really going in for that.
Having pieces written in OO and others in procedural mode is not really
good for me.
Unless we get into a work of rewriting the code into OO Programming,
which would be a HUGE work, maybe highly valuable but I think that
having too many objects without good documentation and entry points
would really be a waste of time and strength.
Let's have this release out and document features and functions.
Then time for OO Programming will come at his own pace.
