after a few hours work, this is the best that i can come up with that doesn't deviate from your original algorithm. It's shorter by some 50+ characters (but still 6 characters over an 80-character, 4-line sig), and i'm sure more could be done; i just don't see what at the moment...

# This has been tested with perl 5.6.1 on Solaris 9 only
@a=map{sub{my$a="push\@s,($_[2]".join($_[1],('(pop@s||1)')x$_[0])."$_[
+3])";sub{
eval$a}}->(@$_)}[1,'','','x2'],[2,'+'],[2,'*'],[0,'',1],[1,'','print c
+hr'];&{$a

• 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 How to display code and escape characters are good places to start.
