I think they were saying that Gleam was Go of functional programming? OCaml may be like Go compared to Haskell but IMHO Gleam really embraces simplicity and pragmatism.
I would say some other reasons OCaml is similar to Go is that the runtime is very simple, performance is on par and the compilation times are very fast. It also markets itself as a GC'd systems language similar to Go. I think a seasoned OCaml would be able to guess the generated assembler code.
I suspect that Gleam is quite different in that regard.
