….to_hash *nil no longer calls nil.to_a, similar to how **nil does not call nil.to_hash. [Feature #21047] This could be optimized more but this matches semantics. The missing optimization is the parser(s) need to see literal `nil` and then set a new flag on build_splat marking that fact. Then the helper can use a cached empty frozen array. The bulk of the improvement is not dispatching so this will be a smaller percentage of improvement on a pretty uncommon case.

Note: I updated Ruby version to 3.5.0 which is not the actual version. This was to match versioning currently used in ruby/spec to hit the specs updated for Ruby 4.0.0. I assume ruby/spec will update this soon and we can sync and change to proper version. |

@enebo The version guards for 3.5 should still run if the version is 4.0. I think the specs have been updated but not synced yet. |
