Really? Where's the array containing arrays come from?

------------------------------------------------------------ Array#assoc
     array.assoc(obj)   ->  an_array  or  nil
------------------------------------------------------------------------
     Searches through an array whose elements are also arrays comparing 
     obj with the first element of each contained array using obj.==. 
     Returns the first contained array that matches (that is, the first 
     associated array), or nil if no match is found. See also 
     Array#rassoc.
