[Haskell-cafe] [Haskell] Call for GUI examples - Functional Reactive Programming

[Paul Liu]

Hi James, I think you meant to reply to the list.

For one, I wouldn't consider GUI programming based on HTML as
declarative, since more often than not, the format says nothing about
its behavior, and when it does, it's through javascript, which is
hardly declarative.

Regards,
Paul Liu
