Sorry, I mean there is now _elegant_ way, which I know. :) Ruby-way,
Ruby-native way, something like that.

I don't like `instance_variable_set` much, but yeah, it's an option.

OK, this looks better. But… doesn't work with `static_cache` plugin and
`Model.first` method.

I have (static cached) locales in DB and in R18n library (from YAML files).
I want to bind them.
So… instead of something like:
```ruby
def r18n
return @r18n if defined? @r18n
@r18n = R18n.locales.find { |locale| locale.code == code }
end
```
I want to make this `find` in initialization (or in `code` setter), once,
also because `Locale` has `static_cache` plugin.
