Your right about the '=='. It's true of all languages I know. Sorry I had nerve surgery on my right arm this last Monday. I still haven't got back to full functionality yet in my right hand and typos are becoming even more common. Plus I would always indent my code, except my phone wouldn't let me enter blank spaces.
Either way, I hope T_high isn't dangerous, just beyond what a reviewer at Cnet would claim to be comfortable. I don't think they should let it get hot enough to actually hurt, but I agree that it should be an option with a disclaimer.
