I’m trying Gleam out right now, and having most recently been writing Go, I’m really loving:
- No nil, instead Option and Result
- ADTs
- Pattern matching + destructuring
- Immutable everything by default
- `use` syntactic sugar (weird at first, but once you’re used to it it’s pretty elegant)
- LSP server works great for such a young language
But most of all I think the overall simplicity of the language is really what’s standing out to me. So far I think the lack of ad-hoc poly and macros are a plus - it really reduces the impulse to write “magical” code, or code with lots of indirections. In the past I’ve definitely been guilty of over-abstracting things, and I’m really trying to keep things as simple as possible now. Though I’ve yet to try Gleam with a large project - maybe I’ll miss the abstractions as project complexity increases.
I suspect Gleam will be a great language for small to medium sized projects written with LLM assistance (NOT vibecoded) - the small language, strong typing and immutability gives good guardrails for LLM-generated code, and encourages a simple, direct style of programming where a human programmer can keep the whole structure in their head. Letting an LLM run free and not understanding what it’s written is I think where projects run into big problems.
