Thank you for your interest in my library.
I've noticed EventSig.scan: val scan : ('a -> 'b -> 'a) -> 'a -> 'b t ->
'a t
Is this function like a fold? Is there a particular reason for naming
it "scan" (rather than "fold")?
Because I thought Haskell's scanl is more similar to EventSig.scan than foldl.
scanl : (a -> b -> a) -> a -> [b] -> [a]
foldl : (a -> b -> a) -> a -> [b] -> a
BTW, I have just noticed Event.scan has a bug. The result of scan function
should
contain initial value specified second argument, but Event.scan doesn't.
That has been fixed.
