λ> item <- generate $ fromRange (1,10)
λ> item
2

Generates a random element over the natural range of a.

λ> import Data.Word
λ> item :: Word8 <- generate pickAny
λ> item

λ> import qualified Faker.Address as AD
λ> item :: Text <- generate $ suchThatMaybe AD.country (x -> (T.length x > 5))
λ> item
Just Ecuador
