File::Temp: Practical Considerations

• Only became core with Perl 5.6.1

• Object-oriented interface is even more recent

• Alternative: require install via Makefile.PL

• Alternative: include under t/ subdirectory

• Least bad alternative: use within SKIP blocks

    SKIP: { 
        eval { require 5.006_001 };
        skip "tests require File::Temp, core with 5.6", (43 - 10) if $@;    
        use warnings;
        use_ok( 'File::Temp', qw| tempdir |);
        my $tdir = tempdir( CLEANUP => 1);
        ok(chdir $tdir, 'changed to temp directory for testing');
        ...
        ok(chdir $cwd, 'changed back to original directory');
    }
