Is the Xscript Process Slow?

The acmscript process is slow because of the downside. Once you put something in jobscript, once that's running in a browser, you can't ever break it. The proposal for this built on madule system actually explicitly says anything that you import from the built in madule system would have a frozen prototype. So we can't get things like smoshgate, or how we have includes instead of contains for arrays,. Because various other juels have already extended the array prototype to have those commonly used words which make sense and were wanted back before they existed.
