- Don`t mutate options, otherwise we end up growing this list in memory. Noticed this because scrooge complains if it receives the same option twice.
Rather than writing a test specific to options on thrift_linter, I'd like to follow up by making option values immutable (at the top level at least), to prevent any other bugs like this.
