> What determines the flight level of understanding you need to function?

The level where r and fl are seen as different letters?

Look, I know this comes off like I'm being an ass, which means I am being an ass, and I'm sorry. I also make many mistakes and need much forgiveness.

I'm also seeing many more innocent typos such as yours on HN. Does it matter? I don't know. Every other response to your question seemed to understand that you meant "right" instead of "flight", but that's also the kind of error, i.e. `if x=1` instead of `if x==1` which is easy to make but not always easy to catch visually when you are looking at the logic internal to the loop.
