[antlr-interest] Problem with ANTLR3.3 and Python 2.7

[Benjamin Niemann]

Hi Jason,

the Python target hasn't been updated since the 3.1.3 release. Using
the runtime with later versions of the tool would probably result in
very subtle errors, so the code does some very strict checking.
I'm working right now on bringing Python back up to speed. In the
meantime you might want to use the 3.1.3 release of antlr from
http://www.antlr.org/download
I also updated the wiki to reflect that.
