The infixed operator + or .+ and the prefixed operator
’+’ returns the term by term sum of two lists.
If the two lists do not have the same size, the smallest list is
completed with
zeros.
Note the difference with sequences : if the infixed operator +
or the
prefixed operator ’+’ takes as arguments two sequences, it
merges the sequences, hence return the
sum of all the terms of the two sequences.
