CodeSOD: Never Don't Stop Not Doing This

It's not nothing to never write confusing English. And it doesn't never influence the code that we write. Don't fail to look at this anti-pattern from today's un-named submitter.

If Not port Is Nothing Then portUnAvailable = FalseEnd If

If the port isn't nothing, then the port isn't unavailable. That's... not untrue. But it is surprisingly confusing when you're reading it in a larger block of code. And, of course, this would be simpler to express as a boolean operation:

portUnAvailable = port is Nothing

Then again, without context, that might be wrong- perhaps portUnAvailable gets set elsewhere and then changes only if Not port Is Nothing. But let's assume that's not how this works, because that hints at a bigger WTF.

Do never don't avoid this pattern in your own code or writing.
