Hi, I'm not sure that I've understood what you need. If you get that array of arrays from a another process @rows and you wish to convert it into a Bag you can do this:
my @rows = [["JF", 1], ["JF", 2], ["MM", 2], ["MPu", 2], ["MM", 2], ["FE", 2], ["FV", 2], ["MPu", 2], ["JP", 2], ["JP", 2], ["FV", 2], ["FV", 2], ["JF", 2], ["MM", 2], ["MPu", 2], ["MM", 2], ["FE", 2], ["FV", 2], ["MPu", 2], ["JP", 2], ["JP", 2], ["JF", 4]]; my Bag $docents = bag @rows.map: -> @row {@row[0] xx @row[1]}; dd $docents; # Bag $docents = ("JP"=>8,"FV"=>8,"FE"=>4,"MPu"=>8,"MM"=>8,"JF"=>9).Bag Otherwise you can start collecting those pairs into a Bag from the start, but we would need more details then.
