Re: Using NLTK3.0 with Jython

Monisha:

Yes, the conversation you cite about __defaults__ refers to something 
that *is* fixed in 2.7b4. (http://bugs.jython.org/issue2183)

Checking up on your first point, the "as" keyword in an except clause is 
a feature of Python from 2.6 onwards. You could replace them all with 
commas, but that isn't necessarily the end of your problems.

I checked "as" out in 2.7, and it is definitely supported in Jython 2.7. 
I found it behaves oddly when used interactively (at the >>> prompt, no 
idea why), but this should not be a problem in NTLK.
