Hi Meir, first of all I should note that your mailer mis-formats the text portion of the E-mail message, which makes it harder to read and follow (along with mis attributions). Please fix it to follow better netiquette.

Hmmm.... there's a world of difference between string-eval and block-eval. I explain block eval here: http://perl-begin.org/tutorials/perl-for-newbies/part4/ What string eval does is evaluate and execute the argument as a Perl expression, so you can construct code at run-time and run it. It can be dangerous when done carelessly, but it has some valid (although rare) uses. Also see: http://en.wikipedia.org/wiki/Eval > > > > Thanks again Shlomi!
