use feature 'say' to print one blank line

[sbk]

How do use the perl-5.10 'say' feature to print a single blank line?

gnat> cat test
#!/usr/bin/perl
use Perl6::Say;
say 'one';
say();
say 'three';

gnat> ./test
one

three
gnat>
gnat> cat ./test
#!/usr/bin/perl
use feature 'say';
say 'one';
say();
say 'three';
gnat>
gnat> ./test
one
Use of uninitialized value $_ in say at ./test line 4.

three
gnat>
gnat> cat ./test
#!/usr/bin/perl
use feature 'say';
say 'one';
say;
say 'three';
gnat>
gnat> ./test
one
Use of uninitialized value $_ in say at ./test line 4.

Pass an empty string.

C:\test>type test.pl
#!/usr/bin/perl
use feature 'say';
say 'one';
say('');
say 'three';

C:\test>test.pl
one

three
