```ruby
require 'ripper'

class BasicParser < Ripper
  EVENTS.each do |event|
    module_eval(<<~RUBY, __FILE__, __LINE__ + 1)
      def on_#{event}(*args)
        puts "#{event}(\#{args.inspect})"
        args.unshift :#{event}
        args
      end
    RUBY
  end
end

require 'pp'

BasicParser.new('a&.b').parse
# in stdout:
# ident(["a"])
# op(["&."])
# vcall([[:ident, "a"]])
# ident(["b"])
# call([[:vcall, [:ident, "a"]], [:op, "&."], [:ident, "b"]])

BasicParser.new('a::b').parse
# in stdout:
# ident(["a"])
# op(["::"])
# vcall([[:ident, "a"]])
# ident(["b"])
# call([[:vcall, [:ident, "a"]], :"::", [:ident, "b"]])
```

On the last line, consistent with `&.`, I would have expected:
```ruby
# call([[:vcall, [:ident, "a"]], [:op, "::"], [:ident, "b"]])
```

This is true for the "operator" argument of `call`, `command_call` and `field`.
Is it intended?
