Here's my guess:

c:\@Work\Perl>perl -wMstrict -le
"use List::MoreUtils qw(any);
 ;;
 sub myfunc { return map { int rand 10 } 1 .. $_[0]; }
 ;;
 my @List_new;
 ;;
 UNTIL_TRUE: {
   @List_new = myfunc(7);
   any { $_ == 3 } @List_new or redo UNTIL_TRUE;
   }
 ;;
 print qq{@List_new};
"
0 1 6 1 8 1 3

Notes:

List::MoreUtils::any() can be replaced with the built-in grep for short lists (for some definition of "short").
any() may also be found in List::Util in later versions of Perl.
The label UNTIL_TRUE is not needed, it's just documentary.

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).
Want more info? How to link or or How to display code and escape characters are good places to start.
