Also possible:

	foreach my $county ('Amador', 'Calaveras', 'El Dorado', ...) {
		<perform actions>
	}

but that does not avoid quotes and commas, the point of the qw// operator.
Escaping the pace using \ does not work, either :-(.

At the risk of being annoying, I will mention that the analogous operator in
Ruby does support just that.

	#!/usr/bin/ruby
	%w[Amador Calaveras El\ Dorado].each do |i|
		puts i
	end

iterates over three array elements as expected, not four.
