A potential security vulnerability in the optional suidperl component
of Perl has been identified. The suidperl is neither built nor

+=head2 Unimplemented (But Recognised) POSIX Regex Features Now Fatal
The unimplemented POSIX regex features [[.cc.]] and [[=c=]] are still
-recognized but now cause fatal errors. The previous behaviour of
+recognised but now cause fatal errors. The previous behaviour of
ignoring them by default and warning if requested was unacceptable
since it, in a way, falsely promised that the features could be used.

found the "concat" a bit surprising when they were doing "just"
variable interpolation.

In some platforms Perl can be configured to use 64-bit integers,
