There's many benefits of having such library in Haskell: improved
automated testing (as Yitzchak Gale mentioned) due to pure nature of
inner algorithms (BrowserAction can be pure and be transformed into IO
only on demand), static typing (just hate a bunch of stupid bugs while
writing all those scripts in python/perl). We can use powerful
HTML/XML parsers available there in Haskell (HXT with its "arrowed"
Haskell community will definitely benefit from such library. Firstly,
as I see, in indirect way: I know many people that don't want to use
or learn more about Haskell, saying it lacks libraries for their
everyday work. Network libraries still aren't "cool" enough, and
personally I want to improve them at least to the point when I can say
"look! here's the network libraries and they aren't worse than yours,
even better: pure and checked!" :). Secondly, new libraries are
useful for the community directly, we have aforementioned lambdabot,
e.g. I'd like to write some bots looking at new changes at
haskellwiki or something like that, thing I'm doomed to code in
