[Haskell-beginners] $ versus .

[Lawrence Bottorff]

I've got this

> init $ tail [1,2,3]
[2]

and this

> chopEnds = init $ tail
> chopEnds [1,2,3]
[1,2]

What happened? Why is it not just init $ tail [1,2,3] ?

This works fine

> chopEnds2 = init . tail
> chopEnds2 [1,2,3]
[2]

What am I missing?
