We couldn't write a type declaration of Circle -> Float because Circle is not a type, Shape is. Just like we can't write a function with a type declaration of True -> Int. The next thing we notice here is that we can pattern match against constructors. We pattern matched against ...
Line 8: 11 elements from circle2 (index 0 through index 10) are copied into circle1 beginning at index 85. This is a legal assignment because the number and type of items are the same. As we mentioned in our brief discussion of enumerated types, the most frequently used type for represe...
