Re: [Haskell-beginners] Would you shed light on "undefined values" please?

Howdy,

I am not clear why "bottom" is an important concept. Would you explain please?

I've been getting into this myself lately. Here's what I've been reading: http://en.wikibooks.org/wiki/Haskell/Denotational_semantics http://blog.ezyang.com/2010/12/hussling-haskell-types-into-hasse-diagrams/ Let us know if you find anything else! Arlen
