Using chrome 21 and prototype 1.7.1, I have discovered that using
$throw $break does not work.
The Error/Exception gets thrown up to the browser when it should have been stopped by if (e != $break)
I suspect that this occurs because inject, each, etc have native implementations in Chrome, and they do not get wrapped by the same functionality as the built in functions
Please tell me that I am wrong, or I will have to change thousands of lines of code to normal for-loops to break out of them.
