Can somebody skilled look at Routes library in python and tell me why there is not python 3 support?
I need Routes functionality for use with Cherrypy on python 3. And I am curious if it will be better to try to port Routes to python 3 or write my own dispatcher for python 3 from scratch. 
I know some porting basics for python 2to3, but if there are any significant problems or drawbacks (other than method names, syntax etc), I would like to know them before I start working on the port.
Thank you very much for any tips!
Edit: 
do not understand me incorrectly! I am not lazy to check it by myself, but there are some aspects that i will not discover until I try it. And maybe, somebody here tried it before :-)
I tried to port Routes to python 3. 
After one day of work, I got all unit tests passed. But the code started being ugly and I was not sucessfull with using ported Routes with Cherrypy (probably something, that is not covered by unit tests). I was not patient enough to debug it.
So I decided to write my own version which I will maybe share as opensource. It is not ready yet and I will update this answer later (for possibly interested people :-)
Thanks to commenters above
