This is one of the bugs jsfunfuzz hits most frequently.

Not just "this". "true", "false", and "null" trigger similar problems: js> (function() { 2 .@ null :: a }) function () { (2).@[null::a]; }

(In reply to comment #1) > This is one of the bugs jsfunfuzz hits most frequently. Never mind, this is easy to ignore with a regexp.

(In reply to comment #2) > Not just "this". "true", "false", and "null" trigger similar problems: actually when there is any namespace for attributes a = function(){ y=x.@ns::attr; y=x.(@ns::attr); y=x.(@ns::attr==5); y=x.ns::y.(@attr==5); } gives ==> function () { y = x.@[ns::attr]; y = x.(@[ns::attr]); y = x.((@[ns::attr] == 5)); y = x.ns::y.((@attr == 5)); } PS: Also please notice that extra parenthesis on last two cases

another testcase a=function(){ y = x.@ns::["attr-s"]; } gives ==> function () { y = x.@[ns::["attr-s"]]; } which is need to solve http://groups.google.com/group/mozilla.dev.tech.js-engine/browse_thread/thread/1271260fc2e3f7b8
