[Haskell-cafe] function arithmetic?

Hi. I was just curious about something. In one of my math textbooks I 
see expressions like this

f + g


(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?
