The only 'variables' I see without `my` in those snippets are formal parameter names, which are declarative only? `say $var;` is equivalent to `print $var . $/;` Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal? "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply] [d/l] [select]

Where is the 'my' in those variable usages? As BrowserUk wrote, I don't see any missing. While we're here I'll take a chance to remind that differently from Perl 5, Perl 6 has `strict` and `warnings` turned on by default except in particular situations, e.g. in oneliners, where it's most often better otherwise. Why did they switch from 'print' to 'say'? It's shorter? Err, well, yes: easy things should be easy. And Perl has been somehow missing a writeln/println statement for quite a long time. But as also pointed out by BrowserUk, they did not "switch": you will have both `print` and `say`. The interesting thing to note here is that iirc in conjunction with the use of the latter auto`chomp` actions are often taken, although it's not entirely clear to me how and when (I know the answer is out there I'm just too lazy ATM) - but it seems that $_ is not chomped by default: `pugs> say .chars for <foo bar baz>; 3 3 3 undef pugs> say .chars for =<>; foo 4 bar 4 baz 4` [download]	[reply] [d/l] [select]
