Integrating reflex-dom with Yesod

[LukeTemp]

In Yesod we have the WidgetFor Monad, within which we can use .julius files to interpolate Haskell values into Javascript for dynamic webpages. For more frontend-heavy pages, it would be nice to use a type-safe DSL rather than relying on Javascript. Specifically, it would be nice if we could add support for timelines in some extension of the WidgetFor monad, e.g., ReflexWidgetFor, rather than having to separate the reflex App from the Yesod widgets and communicate through a port.

Has anyone got experience or thoughts on the complexity of integrating reflex-dom with Yesod in this way? I've used Yesod for a while now but I've only just started learning about reflex, so any comments or thoughts on this are appreciated.
