I find problem in concatenate characters...   
   How concatenate characters in string for List List Characters as   
   z:=[[a,b,c], [d,e,f]]   
   where a,b,c,d,e,f are of type Character   
   In the way one has as result   
   ["abc", "def"]   
   as list of string?   
   It seems return the result but after some warning the follow:   
   [concat(map(x+->x::String,z.i) for i in 1..#z]   
   but it says something not goes in "z.i"
