>Who asked you? Your problem is you think you're a genius and you just can't keep your opinion to yourself.

You don't have a mirror at home do you ? You have described yourself perfectly.
I'm not the one forcing crappy opinions down others' throats.

>>>The second batch of code takes less time to execute and less time to step through in the debugger. It's easier to understand. These are facts, not opinion. A set filter, then a go top is wasteful. Go top is not going to respect the filter, even if it is optimized. Scan does a go top by default.

>>>I write it the second way and have done so for many years, while I see things written the first way far too often. It's not my fault there are programmers who can't tell the difference. They keep holding development back and all the boot-camp wannabees are not improving things.
