Re: [Haskell-cafe] Are there standard idioms for lazy, pure error handling?

[Malcolm Wallace]

 data TerminatedList a e = Then a (TerminatedList a e)
                         | Finally e

Nice.

(So you could do e.g:  4 `Then` 5 `Then` 1 `Finally` "success!".

Errm, you mean:         4 `Then` 5 `Then` 1 `Then` Finally "success!"
