For the package management you're talking about, it sounds like there are two cases:

• Accept any version (1)
• Require a specific version (2)
• Require the latest version (3)

Babushka can already do (1) and (2). The third is fairly easy to add, but to do so in babushka core isn't really feasible until I refactor Babushka::BrewHelper.

For (1), you don't need to do anything: that's the standard behaviour. For example:

benhoskings

  def self.cumulative_by_month model, column
    tally = 0
    count_by_month(model, column).map do |(month, count)|
      [month, tally += count]
    end
  end

  def self.cumulative_by_month_inject model, column
    count_by_month(model, column).tap {|pairs|
      pairs.inject(0) do |tally,pair|

いい練習の番組：
Seinfeld (アメリカ、コメディー)　話が本当にアメリカの形。ユーモアが最高。一番有名なので英語が話せる人とたしかにしゃべれる。
Frasier (アメリカ、コメディー) 一杯あるし、Kelsey GrammerとDavid Hyde Pierceの英語がうまい。
The Office (UKとUSの番組だって、両方ある。とてもいいイギリスとアメリカの比べる事。)
Sherlock (イギリス、) 話がとても速いけど、いいイギリスの英語だと思う。


その他：（これは、僕がちょっとだけ見ましたけど、いい練習だと思う。）
Futurama
House
