The functions as I originally defined them are probably easier for someone new to Haskell to understand what was going on than the rather stark ($ a) in the final factoring of the function... Though the final resulting function is far the cleaner for that notation!
This is what I came up with when I was experimenting: map (\f -> f $ a) fs which then helped me to see it could be rewritten as just map ($ a) fs martin
