+local $xxx ||= $yyy                      applying ||= on a new initialized variable is wrong

+$1 =~ s/xxx/yyy/                         do not modify the result of a match (eg: $1)
+
+$xxx[1, 2]                               you must give only one argument
+
+$xxx[]                                   you must give one argument

+'' || 'xxx'                              <constant> || ... is the same as ...
+
+if ($xxx = '') {}                        are you sure you did not mean "==" instead of "="?
+
+N("xxx$yyy")                             don't use interpolated translated string, use %s or %d instead

+N_("xxx") . 'yyy'                        N_("xxx") . "yyy" is dumb since the string "xxx" will never get translated
