| ListK wraps over the platform `List` type to make it a (type constructor)[/docs/patterns/glossary/#type-constructors]. | ||

| It can be created from Kotlin Sequence type with a convenient `k()` function. |
|

| ```kotlin:ank | ||
| val numbers = listOf(Math.random(), Math.random(), Math.random()).k() | ||
| requests.traverse(Option.applicative()) { if (it > 0.5) Some(it) else None } |
| requests.traverse(Option.applicative()) { if (it > 0.5) Some(it) else None } | ||
| ``` | ||

| requests.sequence(Option.applicative()).fix() | ||
| ``` | ||
