Agreed, but in that case the tool shouldn't be trying to detect what I mean. Why look for 'exit' only so you can print 'no actually, it's exit() dummy'. If you're parsing for it then just bloody do it! Otherwise I'll get a syntax error and realise that 'exit' isn't the right way to exit. And I'll do a quick search myself. But explicitly looking for and detecting my intention and then ignoring it is just dumb.
