Iterators in interesting places? Android KTX adds iterators to ViewGroup and SparseArray

To define iterator extensions use the `operator` keyword. Foreach loops will use the extensions!

Utility methods for a class? Add them to the top level of the source file. In Java, they are compiled as static methods of that class.

Doc: https://kotlinlang.org/docs/reference/basic-syntax.html

Are you defining static constants for your class? Make them top-level properties. They will be compiled to a field and static accessor(s).

Write Kotlin (time * 2) faster with operator overloading. Objects like Path, Range or SpannableStrings naturally allow for operations like addition or subtraction. With Kotlin, you can implement your own operators.
