println(): cannot tell apart empty sequence from sequence with an empty string #119

If we run this EOL program:

Sequence {}.println('Empty sequence: ');
Sequence {""}.println('Sequence with empty string: ');

We will get this misleading output:

Empty sequence: Sequence {}
Sequence with empty string: Sequence {}

We should instead get something like:

Empty sequence: Sequence {}
Sequence with empty string: Sequence {""}
