Ok!
From where can I know this? (where to find that?)
And: why did it work for you, using only require 'activesupport' ?

first search results for 'active_support array extension'

No, it worked with

  require 'active_support/core_ext/array/grouping'

which is _not_ the same as require 'activesupport'.
(which wouldn't work at all).
