Notable Mentions

Most of the utilities and types defined in this module are actually a bit specialized. I’ll highlight a few, however, that find more general use.

• Lists - Efficient utility methods for creating lazy, read-only, views of arrays and other lists. Supports generic type transformations and downcasts.

• TaskStack - Root releaaser (closer) for try-with-resource clause. Is a Closeable and unwinds (pops) the stack by closing other Closeable instances pushed onto its stack. Also supports releasing locks. Use when you need to acquire and release more than one resource; or if you must acquire multiple resources, but only if you succeed in acquiring them all.

• TidyProperties - Writes tidy properties files by allowing you to define the order name/value pairs should appear. The idea is to group related settings near each other. It’s supposed to be human readable after all.
