Is it unsafe to return a pointer to local data?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

No, Perl's garbage collection system takes care of this.

    sub makeone {
        my @a = ( 1 .. 10 );
        return \@a;
    }

    for $i ( 1 .. 10 ) {
        push @many, makeone();
    }

    print $many[4][5], "\n";

    print "@many\n";

[1nickt]: Heh, or they assume that if I want all that I am a "gamer" and I must want red backlighting for the keyboards and that I will pay $3500 ...
