Kotlin Standard Library

The Kotlin Standard Library provides living essentials for everyday work with Kotlin. These include:

Higher-order functions implementing idiomatic patterns (let, apply, kotlin.io.use, kotlin.synchronized, etc).
Extension functions providing querying operations for collections (eager) and sequences (lazy).
Various utilities for working with strings and char sequences.
Extensions for JDK classes making it convenient to work with files, IO, and threading.
