From: PerlFAQ Server on
This is an excerpt from the latest version perlfaq3.pod, which
comes with the standard Perl distribution. These postings aim to
reduce the number of repeated questions as well as allow the community
to review and update the answers. The latest version of the complete
perlfaq is at http://faq.perl.org .

--------------------------------------------------------------------

3.17: Is it safe to return a reference to local or lexical data?

Yes. Perl's garbage collection system takes care of this so everything
works out right.

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

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

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

print "@many\n";

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.

If you'd like to help maintain the perlfaq, see the details in
