  • Gleam is cool. I wrote some services with it to see if I wanted to use it for more projects. It seemed like a good option because it would be easy to teach.

    Things I like:

    • fast build times (I only tested small apps though, under 2000 LOC)
    • strong static types
    • runs on the BEAM
    • easy to learn
    • pattern matching
    • immutable + structural sharing
    • currying (with parameter holes)

    Things I don’t like:

    • no re-exports
    • it’s possible to have name collisions between packages; authors have a gentleman’s agreement to always create a top-level module with the same name as the package
    • some standard library APIs seem missing or immature (it’s still pre-1.0)
    • it can be hard to get good performance out of idiomatic code for specific tasks (see immutability)
    • no format strings; best you can do is "Hello, " <> name. It starts to get cumbersome
    • parsing/serialization is all quite manual boilerplate; there’s nothing quite like serde
    • no field/argument punning
    • no method syntax; you just have to scan the docs to figure out what functions can be used with a given type
    • you can’t define the same variant name twice in the same module; I believe this is a limitation in how the types are translated to Erlang records
    • you can’t call functions in pattern matching if guards
    • you can’t have dependency cycles between modules in the same package
    • hard to write FFI correctly; you lose all the comfort of types












  • So… dev blames skill issues on language? Classic.

    EDIT: For the record, I’m not saying the author is bad at Rust. I’m saying they’re bad at making games and balancing tradeoffs. They keep saying that they don’t like rust because they just want to worry about making a game, not fighting the language. And yet, they seem to continually make decisions that favor performance over ergonomics. Then they whine about how the Rust community is supposedly pressuring them to make bad decisions.
