What you and laz seem to be misunderstanding is that he's saying that mIRC already supports other languages via COM objects, and that the people who want to use other languages can do so.
However, personally I don't like the insinuation that such languages are far superior to mIRC scripting because quite frankly they're not. mIRC scripting is a hell of a lot more focused and able as far as being an IRC scripting language. I can't help but feel that the things people create by using Perl, Python et al. will have little or nothing to do with IRC at all and could just as well be standalone applications.
Also I'm pretty sure CloCkWeRX made a reference to cracking Visual Basic in there somewhere, which of course I don't support.
