HoboSupport - Methodphitamine
A nice hack from Jay Phillips, christened “Methodphitamine”. The low-down is in the original blog post.
>> (1..10).select &it % 2 == 0 => [2, 4, 6, 8, 10] >> %w(a few short words).map &its.length => [1, 3, 5, 5]
its are identical. They just read better in different contexts. Note that methodphitamine is also released directly by Jay (simply
gem install methodphitamine) but it’s small enough that it seemed easier to add it to HoboSupport and avoid an extra dependency. Thanks to Jay.
