Difference between bindElementC and bindElementCO #65

What's the difference between bindElementC and bindElementCO? Most of the code in the functions is the same except the former calls build (element(next)) while the latter uses build (element(store)).

davedawkins commented 1 year ago 
let bindElementC<'T>  (store : IObservable<'T>) (element: 'T -> SutilElement) (compare : 'T -> 'T -> bool)
let bindElementCO<'T>  (store : IObservable<'T>) (element: IObservable<'T> -> SutilElement) (compare : 'T -> 'T -> bool)

It's good question. I remember starting this refactoring to allow composition elsewhere, but the CO version is still making a subscription, and then ignoring next and projecting from the store. I would need to dig a little deeper, and see if the references (K and KO) can be refactored out.
