The below code is some code being written by Xaviar Czervik. It isn't even partly done, and I were a programmer It'd be version 0.00.0.000.0.01, although I don't do that... So, if you're interested on crashing the LSL compiler (This code doesn't compile 99% of the time) check out the code below. And incase you couldn't tell, I don't believe in comments.
