def dups
  tmp_dups = inject({}){|h,v| h[v]=h[v].to_i+1; h}.select{|k,v| v > 1}
  tmp_dups.is_a?(Hash) ? tmp_dups.keys : tmp_dups
end

#smart_sort ⇒ Object

Sorts all items in this enumerable first by non-digits and then by digits.

If a block is given, it will be invoked to calculate the basis for comparison. Otherwise, the items themselves will be used as the basis for comparison.
