Re: [Haskell-beginners] trying to install libraries for Haskell School of Expression

      Plunk! (penny drops)
I get it...now that is truly the icing on the cabal-hell free cake!
Thanks again Julian.

If you go to www.stackage.com/lts/1.10, you'll find a hoogle search box.
It'll give you search results for everything in LTS 1.10.

What does that do for me within LTS confines? I know Hoogle, but I don't
understand what you mean by "they run a hoogle for the exact version,
with every library." ...I just want to understand so I can be as excited as
everybody else right now! LOL :)

It gets better: they run a hoogle for the exact version, with every
library. :)

Took a while to sink in....DEF trying this out tonight
Looks AWESOME if it does what it says!
Getting excited about Haskell again.
THANKS!!!! Yoohoo :)

Just a small note: if you're suffering from cabal hell, LTS Haskell
may help you. I described how to use it here:

Hope someone finds it useful.

Agreed. I will "finish" with a mild semi-demi-rant too regarding the
assumption by a lot of posters that we are all academics with access to
papers on this and that. I am not and I don't. If you cite a paper, make
sure it's available to Joe Public please!
As for only sticking to plain vanialla simple Haskell, yes, that
works BUT there are some many great libraries that a real time
savers...it's such a shame when they won't play well together!
So, despite it all, tonight I will be hacking Haskell !
