SyntaxError: invalid syntax. Maybe you meant '==' or ':=' instead of '='?
error: Failed to build `dependency-source/unstd`
  cause: The build backend returned an error
  cause: Call to `hatchling.build.build_wheel` failed (exit status: 1)

hint: Build failures usually indicate a problem with the package or the build environment
