The first example is simply throwing the result away; this modification simply prints it out instead:

# process analysis rules
foreach( @$analysis_rules ) {
  print eval( $_ ) . "\n";
}

The second example has two errors. Firstly the number of declarations do not match the number of assignments and secondly the argument to return, while syntactically acceptable, doesn't DWIM, because the list will be coerced twice, first into an array and from that to a single scalar. Moreover it will force the return during the first iteration of the loop. The 'map' function provides a rather quick alternative.

# process analysis rules
my @results = map( eval, @analysis_rules );

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
