Assumption of a callback-based, "event driven programming" library is too strong. about reactive-banana HOT 2 CLOSED

Nice to see your tutorial progressing!

But what alternative assumption should reactive-banana make about the "outside world"?

As I see it, FRP is essentially just a fancy way to write callback functions, i.e. things that can be passed to AddHandlers. I'm not very happy with the administrative mumbo-jumbo that is currently needed to hook events in and out of reactive-banana, but it's the simplest one I could come up with so far.

Since you are implementing a custom timer and hence a miniature event-based framework, it seems quite reasonable to me that you have to implement your own machinery with managing callbacks. Fortunately, reactive-banana can help a bit by providing the newAddHandler function.

As /I/ see it, FRP is a fancy way to talk about systems that progress over
time. See herehttp://www.reddit.com/r/haskell/comments/11ixcl/absurd_ambition_towards_lifting/
for
a rank n generalization idea. Maybe doing that actual work can be Kmett's
job, he seems to know what he's talking about.
