=head1 DESCRIPTION
Note that suidperl is neither built nor installed by default in
any recent version of perl. Use of suidperl is highly discouraged.
If you think you need it, try alternatives such as sudo first.

The v1.2.3 syntax is also now legal in Perl.

To cope with the new versioning system's use of at least three significant
digits for each version component, the method used for incrementing the
that with a C<use attrs> pragma in the body of the subroutine.
That can now be accomplished with declaration syntax, like this:
- sub mymethod : locked method ;
+ sub mymethod : locked method;
...
sub mymethod : locked method {
...
}
- sub othermethod :locked :method ;
+ sub othermethod :locked :method;
...
sub othermethod :locked :method {
...
This warns you that C<"fred@example.com"> is going to turn into
C<fred.com> if you don't backslash the C<@>.

+64-bit builds
Subtest #15 of lib/b.t may fail under 64-bit builds on platforms such
as HP-UX PA64 and Linux IA64. The issue is still being investigated.

+Failure of Thread tests
The subtests 19 and 20 of lib/thr5005.t test are known to fail due to
fundamental problems in the 5.005 threading implementation. These are
not new failures--Perl 5.005_0x has the same bugs, but didn't have these
tests. (Note that support for 5.005-style threading remains experimental.)

+NEXTSTEP 3.3 POSIX test failure
In NEXTSTEP 3.3p2 the implementation of the strftime(3) in the
operating system libraries is buggy: the %j format numbers the days of
a month starting from zero, which, while being logical to programmers,
will cause the subtests 19 to 27 of the lib/posix test may fail.
