Ripper.sexp("foo::bar = baz")
# => [:program, [[:assign, [:field, [:vcall, [:@ident, "foo", [1, 0]]], 73, [:@ident, "bar", [1, 5]]], [:vcall, [:@ident, "baz", [1, 11]]]]]]

Note that 73 there. That's either :"::" or [:@op, "::", [lineno, column]] in every other version of Ruby that I could find. I assume this is a backport issue.

I created a PR to fix this https://github.com/ruby/ruby/pull/10610

The issue was with backporting https://bugs.ruby-lang.org/issues/19788
