Yes, you can do that, but you probably shouldn't. See also: http://www.haskell.org/haskellwiki/Num_instance_for_functions http://hackage.haskell.org/package/applicative-numbers On Sat, Aug 31, 2013 at 10:01 PM, Christopher Howard < christopher.howard@frigidcode.com> wrote:
Hi. I was just curious about something. In one of my math textbooks I see expressions like this
f + g
or
(f + g)(a)
where f and g are functions. What is meant is
f(a) + g(a)
Is there a way in Haskell you can make use of syntax like that (i.e., expressions like f + g and f * g to create a new function), perhaps by loading a module or something?
