class Array
# Wraps the object in an Array unless it's an Array. Converts the
# object to an Array using #to_ary if it implements that.
#
# It differs with Array() in that it does not call +to_a+ on
# the argument:
#
# Array(:foo => :bar) # => [[:foo, :bar]]
# Array.wrap(:foo => :bar) # => [{:foo => :bar}]
#
# Array("foo\nbar") # => ["foo\n", "bar"], in Ruby 1.8
# Array.wrap("foo\nbar") # => ["foo\nbar"]
