Gleam doesn't compile to Erlang source anymore

Gleam’s v1.19 release changes its Erlang backend to generate abstract forms instead of Erlang source, significantly improving compile times and making error locations and stack traces more accurate. For CIOs and technology leaders, this matters because faster builds and better diagnostics can shorten delivery cycles, reduce developer friction, and improve operational reliability for teams using BEAM-based systems. The strategic takeaway is that language/runtime tooling choices can materially affect engineering productivity and maintainability, so platform decisions should account for compiler architecture, not just language features.
