Worked on the andiwand/acts repository to refactor user-defined literal operators within the Acts library, focusing on compatibility with clang-20. The approach involved standardizing the hashing function signature and updating unit literal constants to ensure consistent naming conventions throughout the codebase. By addressing syntax issues specific to modern toolchains, the changes improved build reliability and simplified future maintenance. The work was implemented using C++ and centered on library development practices, with all modifications tracked in a targeted commit. This update enhanced the stability and usability of the Acts library, supporting ongoing development and integration with up-to-date compiler environments.
