      Subject: eval() performance
      Date: Sat, 09 Dec 2000 00:38:11 GMT

      I've been taking a look at some old Perl code, written by
      someone else.  The main part of the app does the following
      (it's a CGI script):

      1 Read in a certain CGI parameter
      2 Based on this parameter, open() a certain Perl script as a
      text file and read the contents into a single scalar variable
      3 Use the following code to evaluate the loaded code:

      eval $code;
      if ($@) {
           #handle errors
      }

      My question is: how would you improve this? My first
      thought was to use an eval block - i.e.

      eval {$code;};
      if ($@) {
           #handle errors
      }

      Would this improve performance?

Good question
Unfortunately, things started to go awfully wrong at that point
