Adding an extra level of indirection with eval does noth solve the problem. eval returns the value of the last expression evaluated, but that last expression would return the same value without the help of eval:

$x = 1; $y = 2; $return1 = $x + $y;
$return2 = eval { $x = 1; $y = 2; $x + $y }

If particle already knew what that last expression should be, to get the value he wants, using eval wouldn't gain him anything.

I know how to get STDIN and STDOUT, or STDIN and the exit value, but I can't figure out how to get STDOUT, STDERR, and the exit value. :(

• 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).
