'External content' widget

[BartAdv]

Would it be doable to implement widget which renders the raw content (html), and then hooks to some URL, and when request arrives there it process it, generate some value and pass this value down the flow?

This could allow to 'escape' the nice-but-often-restricting applicative/monadic land in favour of traditional approach.

Pseudocode:

external uri = do
  sendResponse "<input type='button' onclick="this.form.submit()">foo</input"
  resp <- waitForResponse uri
  x <- processResponse resp (to produce meaningful value from raw HTTP request)
  return x -- could even loop here again to 'external'

test = page $ do
  i <- getInt Nothing
  e <- external "/baz" -- this won't pass further unless there will be request ready at the specified URI
  -- ...

Hah! This looks waay simplier than what I've envisioned, and should just do the trick - thanks.
