It blocks code tags from using other programming languages
Often, a user will post only a snippet of code, which will not work under strict, or perhaps even without it (one such example is in the next point), and would be very annoying to try to get working
It's a severe security risk, since BEGIN blocks are still executed under the -c switch
What's wrong with pseudo code, anyway?
