By rgabo:

If you look at the last line in the diff (`cattr_accessor :ignored_assigns`), there is a class variable attribute accessor which means you can just call `AssignsNote.ignored_assigns` which is just an array. I used `Array#concat` but could've used `<<` or `+` or `+=`. The intention was to not allow replacing the array altogether, but there is a typo in the code (`instance_writter` vs `isntance_writer). Easiest would've been:

`cattr_reader :ignored_assigns`
