+(W unpack) You tried something like

+=item Deprecated use of my() in false conditional
+
+(D deprecated) You used a declaration similar to C<my $x if 0>.
+There has been a long-standing bug in Perl that causes a lexical variable
+not to be cleared at scope exit when its declaration includes a false
+conditional. Some people have exploited this bug to achieve a kind of
+static variable. Since we intend to fix this bug, we don't want people
+relying on this behavior. You can achieve a similar static effect by

=item Malformed UTF-8 character (%s)
-Perl detected something that didn't comply with UTF-8 encoding rules.
+(W utf8) Perl detected something that didn't comply with UTF-8 encoding rules.
One possible cause is that you read in data that you thought to be in
UTF-8 but it wasn't (it was for example legacy 8-bit data). Another
Perl thought it was reading UTF-16 encoded character data but while
doing it Perl met a malformed Unicode surrogate.

They're written like C<$foo[1][2][3]>, as in C.

-
-(W printf) There is a newline in a string to be left justified by
-C<printf> or C<sprintf>.

-The padding spaces will appear after the newline, which is probably not
