The say command.

Examine what is said, not who speaks.

Silence betokens consent.

Love the truth but pardon error.

I've tried Perl6::Say, but found it wanting. The list of caveats regarding the type of filehandles it will work with is annoying. I tend to store file handles in hash elements quite frequently, and use indirect object notation `print { $fhs{INPUT} } $stuff;`, and that doesn't work with P6::Say. I'm not ready to give up the simplicity of that notation and move to `$fhs{INPUT}->say ...`. If filehandles were truely OO constructs, complete with independant settings for `$/, $\, $=, $., $^ etc. etc.`, then it would be a different matter...but they aren't. If say were implemented within the language, it would be barely any code at all. Just a stub sub, pp_say, that localised $\ and set it to "\n", and then calls pp_print() would probably be all was required, but it would 'Just work'. I think it would be a very useful addition to Perl5--but then I'm biased against having to add zillions of ."\n"s :) Examine what is said, not who speaks. Silence betokens consent.

I'd definitely like to see `say` in Perl 5. After the `//` operator (which is already slated for 5.10), I think `say` is probably the biggest "bang-for-the-buck" in all of Perl 6. As for Perl6::Say being "wanting", I would agree. Unfortunately, Perl 5's import and subroutine prototype mechanisms aren't quite up to the task of implementing a full `print`-like syntax. If only I could do it in Perl 6. Oh, wait... `;-)`	[reply]

Isn't say just as simple as adding 'say' as a keyword to keywords.pl in the Perl source, recompiling, then doing: `*CORE::GLOBAL::say = sub { print @_, $/ };` [download] Being right, does not endow the right to be rude; politeness costs nothing. Being unknowing, is not the same as being stupid. Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence. Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.	[reply] [d/l]

Not quite. For a start, $/ may not be set, or could be set to \42 or ... Examine what is said, not who speaks. Silence betokens consent. Love the truth but pardon error.	[reply] [d/l]
