[Haskell-beginners] FRP

Hi. I'm trying to understand what Functional Reactive Programming is, or, more properly, what distinguishes it from "regular" functional programming, and what it would look like if I were to program in a "FRP Style", i.e., without some mysterious FRP module hiding the details. After reading a bunch of links and even looking at some source code I'm still not clear on this. If I program in an event-based style, and have data structures updating over time, with some data structures dependent on others for their values, and I use a functional language, is that FRP? Or is there some essential element I'm missing here? -- frigidcode.com indicium.us
