# Chef Infra Client 16.5 introduced performance enhancements to Ruby library loading. Due to the underlying implementation of Ruby's `.to_yaml` method, it does not automatically load the `yaml` library and `YAML.dump()` should be used instead to properly load the `yaml` library.
#
# @example
#
# # bad
# {"foo" => "bar"}.to_yaml
#
# # good
# YAML.dump({"foo" => "bar"})
