The extensions 'contains' and 'reversed' from kotlin.ranges can be more specific for IntRange, LongRange, etc than the same functions from kotlin.collections, yet they lose in overload resolution to the latter ones when invoked from kotlin.collections package because of same package package extensions are preferred (KT-30633).
Code Generation for Standard Library
Some of the code in the standard library is created by code generation based on templates.
For example, many Array methods need to be implemented separately for Array<T>, ByteArray, ShortArray, IntArray, etc.
To run the code generator use the following command in the root directory of the project:
./gradlew :tools:kotlin-stdlib-gen:run
Note: on Windows type
gradlewwithout the leading./
This then runs the script which generates a significant part of stdlib sources from the templates authored with a special kotlin based DSL.
