Re: [Haskell-beginners] if ands

Also, an nice way to check how evaluation works in ghci is to do something like:

if False && error "error here" then "it's true" else "it's false"

This expression will evaluate as "it's false" without any "error here" error message appearing On Thu, Nov 5, 2009 at 9:05 PM, Nathan M. Holden wrote:

If you have an if statement like

if (a&&b) then fun else fun'

and a is false, does GHC actually bother to check b? _______________________________________________ Beginners mailing list Beginners@haskell.org http://www.haskell.org/mailman/listinfo/beginners
