NAME ^

Perl6::Say - Implements the Perl 6 say (print-with-newline) function

SYNOPSIS ^

    # Perl 5 code...

    use Perl6::Say;

    say 'boo';             # same as:  print 'boo', "\n"

    say STDERR 'boo';      # same as:  print STDERR 'boo', "\n"

    STDERR->say('boo');    # same as:  print STDERR 'boo', \n"

    $fh->say('boo');       # same as:  print $fh 'boo', "\n";

DESCRIPTION ^

Implements a close simulation of say, the Perl 6 print-with-newline function.

Use it just like print (except that it only supports the indirect object syntax when the stream is a bareword). That is, assuming the relevant filehandles are open for output, you can use any of these:

    say @data;
    say FH @data;
    say $fh, @data;
    FH->say(@data);
    *FH->say(@data);
    (\*FH)->say(@data);
    $fh->say(@data);

but not any of these:

    say {FH} @data;
    say {*FH} @data;
    say {\*FH} @data;
    say $fh @data;
    say {$fh} @data;

Interaction with output record separator

In Perl 6, say @stuff is exactly equivalent to Core::print @stuff, "\n".

That means that a call to say appends any output record separator after the added newline (though in Perl 6, the ORS is an attribute of the filehandle being used, rather than a glonal $/ variable).

WARNING ^

The syntax and semantics of Perl 6 is still being finalized and consequently is at any time subject to change. That means the same caveat applies to this module.

DEPENDENCIES ^

None.

BUGS AND IRRITATIONS ^

As far as I can determine, Perl 5 doesn't allow us to create a subroutine that truly acts like print. That is, one that can simultaneously be used like so:

    say @data;

and like so:

    say {$fh} @data;

Comments, suggestions, and patches welcome.
