Agreed, but there's no requirement for it to be instantiating
something (although that will be common). "dict()" is an expression
that you want to evaluate five (or however many) times. It might just
as easily be some other function call; for instance:

head1,head2,head3=file.readline()

to read three lines from a file. Or it mightn't even be a function call per se.
