details on this 9.80 thing: http://dev.opera.com/articles/view/opera-ua-string-changes/

i went with this regex approach mostly for consistency..

the alternative is using window.opera.version(), which is supported in opera 7.6+, though we wouldnt have the useragent unit tests against it, obviously.

} else if (/Opera/.test({}.toString.call(window.opera)))
  ret = { browser: "opera", version: opera.version() };

So you went with the more brittle solution ?
Opera has proven that it doesn't mind changing the UA string so why rely on it when the alternative smaller/more reliable solution exists ?
Consistency can take a back seat here. A toString variable already exists in your primary closure so no need to use {}.

If I were using a RegExp, I'd do something more like..

} else if ( matches = /^(opera).*(?:version)?/(\d+.\d+)/.exec( ua ) ) {
ret = { browser: matches[1], version: matches[2] }
}
