It's defined, such as it is, in ext/B/B.{pm,xs} in the perl
distribution. An object of class B::SPECIAL represents one of the magic
internal Perl objects, such as the 'undef' value. It doesn't define a PV
method.
Which version of Perl, and which version of B::Lint, are you using?
There have been several updates to B::Lint recently: it might be worth
upgrading. If that doesn't help, you've found a bug; reduce it to a
*minimal* testcase and report it at rt.cpan.org.

Subject: cgi_bin
Message-Id: <KfwY8iknDfGHFA3B@maproom.demon.co.uk>
When I first wrote Perl cgi scripts to run on web sites, I was told to
put them in a directory called cgi_bin. I did so, assuming either that
the name of the directory was significant, or that the cgi_bin provided
by the web host has some magic property.
As I have written more scripts and used more servers, I have come to
realise that this is not at all necessary. I can put a cgi script
wherever I like, just as I can a .gif file. There is no magic involved.
So why did books and web hosts once encourage the use of a directory
called cgi_bin? Have things changed, or was it always irrelevant where
you kept your cgi scripts?

This is a question about which webserver you are using, how it is
configured, and best practices for structuring web sites.
It has nothing to do with Perl and you may get much better responses asking
a NG that actually deals with web servers and web sites.

It's only good enough for the girls I go with. You cats have C as a

Does Fortran, the common C extension, exist for perlers?

Have you read the `perldoc perlhack` that was mentioned earlier?
If not, I commend it to you.
If you have, I don't understand why you'd post this assertion here.

Bugs can be anywhere in the implementation. "Perl" is the language,
"perl" is the binary.
The documentation is (supposed to be) equal on all platforms, the binary
"of course" is not.
So a bug can for example be documentation-specific, or
platform/binary-specific.
Bugs can be documented, for example as "known, will not be fixed anytime
soon".
Bugs get fixed all the time. See also perlbug, which BTW doesn't mention
documentation bugs.
So if your 'perl' fails a test, or if the documentation and the program
disagree, please report the bug.

I still don't understand how you define 'language' here. There is
nothing to "admit". The Perl language is just never meant to be defined
in the sense that you seem to be looking for, if I interpret the
background of your question to your liking. :)
Perl is defined by its implementation, and that has proven to work very
well in many ways, and not so well in many other ways.
Remaining backwards compatible (which is another definition in itself),
is both loved and hated by many p5-ers. Back-porting is still actively
done, for early Perl 5 versions, and for many platforms.

Do you find that so disserviceable to the community? FWIW my personal
experience is the Larry and others mostly got it right: occasionally
this is not the case, but I can live with it.

i think wade is reenacting the attack on perl harbor with the ladies
auxillary. (otherwise known as mud wrestling :).
as for wanted a formal ISO/ANSI spec, that is hilarious. has he ever
actually seen one? i worked on compilers with the ANSI PL/I spec and i
still haven't recovered from the loss of brain cells.

I appologize for my limited imagination, but I don't see any possible
relation between the computer programming language Perl and/or its
implemention on the one side and PPL and the ICAO on the other side. Would
you mind to elaborate, please?
Are you e.g. suggesting that programmers who want to use Perl must have 40
hours of mandatory training by a licensed instructor and pass a written,
oral, and practical test administered by a government official before they
are allowed to use Perl, just like it is required for a PPL?
Or are you e.g. suggesting that Perl programmers must pass a biyearly
medical exam as required for a PPL?
Or are you e.g. suggesting that Perl programmers must pass a biyearly
proficiency test as required for a PPL to be allowed to continue to program
in Perl?
