This method may be useful for example to easily accept both symbols and strings as options. For instance `ActionText::TagHelper` defines
```ruby
def rewrite_path(options)
def rich_text_area_tag(name, value = nil, options = {})
options = options.symbolize_keys
options.update(options[:params].symbolize_keys) if options[:params]
options[:input] ||= "trix_input_#{ActionText::TagHelper.id += 1}
...
end
```

The third line can safely access the `:input` key, and let the user to pass either `:input` or "input".
