While Elixir doesn't make use gen_statem itself, I believe its utility makes it worthwhile supporting first-class in Elixir.
First-class support specifically entails: - A GenStatem module in Elixir's standard library - Comprehensive documentation - Inclusion in the default Logger.Translator In brief, gen_statem's utilities have proven particularly useful for client libraries: - Managing cyclomatic complexity with state transitions - Postponing events until the necessary state's situated to process them - Comprehensive and easy to use timeouts - Ensuring systems operate in a predictable manner A few prominent libraries using gen_statem today include: - elixir-ls - finch (req by extension) - xandra - nostrum - postgrex (Phoenix by extension) - livebook I believe inclusion in Elixir's standard library would: - Improve visibility and accessibility, thereby encouraging usage - Prove a potentially pivotal asset to those wanting to author Elixir libraries - Overall contribute to ecosystem growth and language adoption - Remove existing pitfalls with gen_statem not logging crashes properly I don't believe any of the above merits unto themselves justify including gen_statem in Elixir. However I think it differentiates itself in a few key ways that move the needle: - It and gen_fsm before it are a key part of OTP's model of fault tolerance - Its merits and performance overhead are well understood - It is reasonable in scope to include in the language itself -- You received this message because you are subscribed to the Google Groups "elixir-lang-core" group.
