Re: [Haskell-beginners] Is there an idiom for this?

You can be cute and use the applicative instance on functions: (&&) <$> pred1 <*> pred2. I would recommend against such cuteness however and just write out the arguments. On Mon, 16 Nov 2015 at 11:54 emacstheviking wrote:

I guess it depends on the final use cases... you could use currying to partially evaluate some stuff ready, locked and loaded as it were but the example you have given shows to distinct functions pres1 and pred2.

I guess the short answer is "yes" but it depends on how you do it!

Suppose I want to use an argument twice, as for example in the expression: (\x -> (pred1 x) and (pred2 x))

Is there a shorter way of doing this? _______________________________________________ Beginners mailing list Beginners@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
