Yes, you just reopen the class and add/override your method. For example, a
nice randomisation method for arrays:
class Array
def randomise
sort_by { rand }
end
def randomise!
self = randomise
end
end
(Takes unfair advantage of Ruby's practice of defaulting a call without an
object to sending to the current object)
