the "not" operator is a more loosely binding version of !<br><br>because && is stronger the first statement would evaluate as<br><br>not ($foo && ($bar ne "") )<br><br>If you use ! instead of not both statements would be equivalent.<br>

What is the difference between:<br>
<br>
if (not $foo && $bar ne "") {}<br>
if ((not $foo) && ($bar ne "")) {}<br>
<br>
I assumed it was mainly an aesthetic/readability thing, but I realize that no, it's logically different. Thanks for enlightening me?<br>
