Re: [Haskell-beginners] What is the Haskell idiom for "if then else if then"

That works, but I guess a case statement would be nicer: case compare r 0 of LT -> LEFT GT -> RIGHT EQ -> STRAIGHT This uses the compare function, which results in a value of the Ordering datatype, which consists of the constructors LT, EQ and GT. Peter Hickman wrote:

I've just written this piece of code

if r < 0 then LEFT else if r > 0 then RIGHT else STRAIGHT

which works just fine but it does look rather clunky (as it would in any language I suppose). Is there a Haskell idiom for this type of code?
