thank you for uploading this great tutorial. Your efforts really make abstract concepts a breeze.

I love how you corrected my mistake I thought bind lowered the result of the function, For instance String -> Optional String then bind lowered the result to fit into another String -> Optional String function. This creates a zig-zag pattern and of course this is a code smell. Thank you for the correction. Now I understand that it lifts the function instead.

Didn't clearly understand the applicative scenario. Can you provide any further resources I can read up on about it? Appreciate your effort!

Can't we get rid of the 0 case in isPositive function? Because if the input is 0, then bind won't call the isPositive function, essentially removing the need for checking 0? match num > 0 with | 0 -> None | 1 -> Some true

I think it would defeat the purpose of this contrived example. Rewatching the video, I feel its a very poor example. Check fsharpforfunandprofit for a better explanation.

I always thought of map as like this in an OO language a = Box(5).map(square) and result is Box(25). This might be wrong of course.
