Re: svn commit: r705780 - in /incubator/shindig/trunk: ./ java/common/src/main/java/org/apache/shindig/auth/ java/common/src/main/java/org/apache/shindig/common/xml/ java/gadgets/ java/gadgets/src/main/java/org/apache/shindig/gadgets/ java/gadgets/sr
Given that Neko is demonstrably faster, and if I understand your results,
equally lenient w/ input (if not better), I'd vote to enable it by default.
We haven't even made the parse-based rewriter the default yet -- Neko gets
us close to, or arrived at, being able to do so.
