I got the following errors after applying Scherer's Python 3 pull request.
The webhelpers.html.tags.Options failures are due to another patch, so just fix the test to match the expected (change strings to ints). But the other problems look like Python 2/3 issues.
I asked on the pylons-discuss list yesterday if anyone would like to take over WebHelpers so I can focus on WebHelpers2. Would you and/or Wolfgang like to do this? If so, email me a reply to that list message.
