If I wasn't so lazy I'd go into a long rant on why I disagree with you, but I don't think it's worth the time or energy. I am just going to say this:
Not everyone writes malicious code. Maybe you've been under a rock somewhere, but there are programs called "virus scanners". Maybe you've heard of them? If mIRC Scripting was a compiled language, anti-virus companies could add support for mIRC scripting.
It's a wonder you actually use Microsoft Windows and mIRC knowing they both are not open source. Afterall, how do you know what's actually going on in the code since you cannot view it? mIRC is for Windows. The majority of Windows applications are closed source. If you like open source so much, why not use *NIX? There are many IRC clients that run under *NIX operating systems that are fully open source.
There many benefits of compiled code. Some of the benefits are:
1. Less CPU and system resource usage.
2. Compiled code runs much faster.
3. No more having to worry about your script being ripped or modified with an integrated backdoor.
Finally, I just want to say that I am all for a closed source mIRC Scripting language.
