Safer Scripting Through Precompilation

I’m going to talk about putting capabilities into scripting languages. The reason that you might want to put capabilities into a scripting language is because it would be good if we could get a script from any old place and run it without being worried that it was going to do something nasty to us, and more than that, we would like the script to do things that were actually useful, to read and write files, and make network connections, and all the things that we expect programs to be able to do, but only exactly what we want it to do.
