Dear Haskellers,

I'm enjoying Haskell.

After FTP(Foldable/Traversable in Prelude proposal),

newcomers encounter Foldable signatures in their early stage.

So I drew a few simple illustrations about a type introduction for newcomers/casual haskellers.

If I have misunderstood, please teach me. I'll correct them.

Thank you =),
