Depends. You can also collect them in a table (with "{...}") or directly
into variables (with "a,b,c = ..."), if you know how many of them you
want.

Yes. For small number of arguments (say, less than five) this quadratic
behavior is not relevant. For larger numbers, it is cheapter to
create a table.
