[Haskell-cafe] Find a point inside (x,y,z) -> Bool

[Imants Cekusins]

> finding points inside a shape

Any hints about how a point thus found would be used?

if any such point is fit, why not make a ref point part of shape
definition: define the shape as

type Coord= (Int,Int,Int)
type IsWithin=Coord ->Bool
type Shape= (Coord, IsWithin)
