The MRI commit: ruby/ruby@3a3f48f

Btw, should we unexclude test_syntax.rb (tag only individual failed tests)? The file completely disabled by failing.exclude but it is runnable:

jt test test/mri/tests/ruby/test_syntax.rb

Finished tests in 106.157000s, 1.0550 tests/s, 10.3620 assertions/s.
112 tests, 1100 assertions, 26 failures, 3 errors, 0 skips

Yes, that's a good thing if it works and if we can exclude the failures (there is tool/parse_mri_errors.rb for convenience + jt retag).
