Good or Bad: Writing Tail Recursion in Elixir

The content delves into the practice of writing tail-recursive functions in Elixir and other BEAM languages, highlighting the author's preference for creating their own implementations for readability, modularization, and documentation purposes. While Elixir provides constructs like `Enum.reduce` that internally use tail recursion, the author feels that custom tail recursion makes the code clearer and easier to manage. A comment from another user, sisyphus, suggests that writing tail-recursive functions isn't necessarily bad but can be if done for the wrong reasons, such as premature optimization. The discussion centers on the trade-offs between using the language's built-in abstractions and the perceived benefits of tail recursion written by developers themselves.
