+(S) This warning indicates something wrong in the internals of perl.
+Perl was trying to find the class (e.g. LISTOP) of a particular OP,
+and was unable to do so. This is likely to be due to a bug in the perl
+internals, or due to a bug in XS code which manipulates perl optrees.

+In Perl 5.30, it will no longer be possible to use sysread(), recv(),

=item "%s" is more clearly written simply as "%s" in regex. This will be a fatal error in Perl 5.28; marked by S<<-- HERE> in m/%s/

+(D deprecated, syntax) The special variable C<$*>, deprecated in older
+perls, has been removed as of 5.10.0 and is no longer supported. In
+previous versions of perl the use of C<$*> enabled or disabled multi-line

+
+Instead of using C<$*> you should use the C</m> (and maybe C</s>) regexp
+modifiers. You can enable C</m> for a lexical scope (even a whole file)
+with C<use re '/m'>. (In older versions: when C<$*> was set to a true value
+then all regular expressions behaved as if they were written using C</m>.)

(D deprecated) You tried to use one of the string bitwise operators
(C<&> or C<|> or C<^> or C<~>) on a string containing a code point over
0xFF. The string bitwise operators treat their operands as strings of
bytes, and values beyond 0xFF are nonsensical in this context.
