Sorry, it should have been arrays.zip_many above.

Feature #6499: Array::zip

Sometimes it's more natural to have Array::zip rather than Array#zip. Otherwise first array of list became unnecessary dedicated
For example 
cols = first_row.zip(second_row,third_row,fourth_row)
have more natural analog:
cols = Array.zip(first_row,second_row,third_row,fourth_row)

Implementation is obvious:
def Array.zip(first,*rest)
  first.zip(*rest)
end
