What is the problem this feature would solve?

Make Bun compatible with modern Typescript by supporting decorators.

Stage 3 decorators was approved about three years ago.

Microsoft released Typescript 5.0 about two years ago with decorator support enabled by default. The old experimentalDecorators flag now switches support from the default stage 3 design back to the previous stage 2 design. They are not compatible.

What is the feature you are proposing to solve the problem?

See https://2ality.com/2022/10/javascript-decorators.html

What alternatives have you considered?

Use the old.
