It doesn’t have macros, which are one of Elixir’s most important features. Even if you rarely write macros yourself in application code, the most popular libraries in the ecosystem (Ecto, Phoenix, Absinthe, etc) make heavy use of them. The popular DSLs they provide wouldn’t otherwise be possible.
But I guess only time will tell.
I think it's a bit strange to bring up macros here. There are lots of languages that don't have Elixir's macro system, and they're doing fine.
I was just going by that.
Re: macros, I brought them up because their absence was a reason I wasn’t drawn to the language when I checked it out a few years ago. I really do think macros are a big deal and all the other newer languages I use, such as Rust, have them or some kind of meta-programming features.
I didn't. I said don't use Gleam and then said why.
I care about having ergonomic DSLs and a RAD web framework that's maximally productive for individuals and small teams. Others care about different goals. As I said above, I'm also glad Gleam exists and people have more options.
