Still on the subject, according to LYH, the above definition(?) is read 
thusly: "fmap takes a function from one type as to another and a functor 
value applied with one type and returns a functor value applied with 
another type".

So if list is "a part of the part of the Functor type class" (quoting 
LYH) how am I to grok a list e.g. [1,2,3] as a "functor value applied to 
a type"?

Thanks,
