But I'm having problems with one of the functions:

func3 f l = l ++ map f l

While we're at it: The best thing I could come up for

func2 f g l = filter f (map g l)

is

func2p f g = (filter f) . (map g)

Which isn't exactly point-_free_. Is it possible to reduce that further?

Similarly: lambdabot> pl func2 f g l = filter f (map g l) func2 = (. map) . (.) . filter :)
