See perldoc feature.
[code]
#!/usr/bin/perl
use strict;
use warnings;
use feature qw(say);
say "Hello!";
[/code]
This prints "Hello!" followed by a newline.
You can also do:
[code]
#!/usr/bin/perl
use strict;
use warnings;
use 5.010;
say "Hello!";
[/code]
Which enables all the 5.010 features.
Hope that helps. You are right that the documentation may need to be clearer
to the uninitiated.
