+# e.g.: (taken from CPAN's documentation)
+# open($handle, '>', $filename); #not ok

+# This rule states that each system call should have its return value checked
+# The problem is that it includes the print call. Checking every print call's
+# return value would be harmful to the code readabilty.
+# This configuration keeps all default function but print.
