:: [a] -> Int -is:exact -is:exact -is:exact -is:exact -is:exact -is:exact -is:exact is:exact

Gives the length of the list.
Returns the size/length of a finite structure as an `Int`. The default implementation is optimized for structures that are similar to cons-lists, because there is no general way to do better.
Get the scale of a `Numeric` as an integer. For example, `numericScale (3.14159 : Numeric 5)` equals `5`.
