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?
Not the syntax, but the notion itself corresponds exactly to idiom brackets/applicative functors. In this case it's the Reader applicative. Roman
