Do you want to use compose in a project that uses reflection (e.g. gson or moshi)? Please star the issue. I don't believe a P4 priority is justified as reflection is super common and just enabling compose (not even using it) causes a runtime crash (minimal reproducible project is included) and this is still not working with alpha07.
