Unless you fully understand the differences between the high and low-precedence operators, it is easy to misinterpret expressions that use both. And even if you do understand them, it is not always clear if the author actually intended it. .PP .Vb 3 \& next if not $foo || $bar; #not ok \& next if !$foo || $bar; #ok \& next if !( $foo || $bar ); #ok .Ve .SH CONFIGURATION .IX Header "CONFIGURATION" This Policy is not configurable except for the standard options. .SH AUTHOR .IX Header "AUTHOR" Jeffrey Ryan Thalhammer .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright (c) 2005\-2011 Imaginative Software Systems.
