Mneme: Elixir Snapshot Testing Tool

Zach Allaun has introduced an Elixir library called Mneme, aimed at facilitating snapshot testing for programmers. He describes the tool as something he enjoyed working on and believes will be useful to others. The tool's resources include a one-minute demo, documentation, and the package available on Hex and GitHub. Users are encouraged to provide feedback or submit issues. Throughout the discussion thread, there are exchanges where Zach responds to user feedback, implementing fixes and improvements to the library. Key updates include performance optimizations, a `:restart` option for `Mneme.start/1`, and a `:default_pattern` configuration for auto-assertions to streamline the test development process. Zach also mentions a future screencast and his enjoyment of a REPL-driven development workflow supported by the new tool.
