# HoboSupport - Methodphitamine

## `Kernel#it` and `Kernel#its`
A nice hack from Jay Phillips, christened "Methodphitamine". The low-down is in the [original blog post][1].

>> (1..10).select &it % 2 == 0
=> [2, 4, 6, 8, 10]
>> %w(a few short words).map &its.length
=> [1, 3, 5, 5]
Note that `it` and `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.
