fig 10.5: is the flatMap type chart correct? #172

Open marko-asplund opened 4 years ago

Type A is represented with a circle and B with a star. In the flatMap parameter chart these seem to have switched.

The diagram does have a A => F[A] part, which doesn't match the referenced code snippet. But the second (A => F[B]) and third (B => F[C]), do match the A = circle, B = star convention.
