unfoldable :: forall m f a. MonadRec m => MonadGen m => Unfoldable f => m a -> m (f a)
Creates a generator that produces unfoldable structures based on an existing generator for the elements.
The size of the unfoldable will be determined by the current size state
for the generator. To generate an unfoldable structure of a particular
size, use the resize
function from the MonadGen
class first.
