class Array
# Converts a two-element associative array into a hash.
#
# a = [ [:a,1], [:b,2] ]
# a.to_h #=> { :a=>1, :b=>2 }
#
# If +arrayed+ is set it will maintain trailing arrays.
#
# a = [ [:a,1,2], [:b,3] ]
# a.to_h(true) #=> { :a=>[1,2], :b=>[3] }
#
# NOTE: the use of a values parameter has been deprecated
# because that functionality is as simple as:
#
# array1.zip(array2).to_h
#
def to_h(arrayed=nil)
unless arrayed
Hash[*self.flatten]
else
h = {}
each{ |e| h[e.first] = e.slice(1..-1) }
h
end
