Michael I didn't even know it existed.

I do, every time I forget to hit the shift key around certain invocations
of Data::Dumper and then wonder why my program is core dumping.

Doh!

Get rid of it completely.

I think that, for the rare occasions people want this functionality, one
of the many O (B) modules should offer it, at least in spirit.

one use of a dump type of thing (if it could be made to work) is for the
Perl without perl idea that schwern asked about. this would then be a
form of perlcc without paying for it. i agree that it should be a module
that can be loaded to create a preloaded binary image which can be run
directly.

but dump isn't the way to go as it is broken, you need a flaky undump
program (from emacs), it is not portable, etc.

RFC 267 (v1) Eliminate dump() function

[Perl6 RFC Librarian]

This and other RFCs are available on the web at
  http://dev.perl.org/rfc/

=head1 TITLE

Eliminate dump() function

=head1 VERSION

  Maintainer: Dominus [EMAIL PROTECTED]
  Date: 20 Sep 2000
  Mailing List: [EMAIL PROTECTED]
  Number: 267
  Version: 1
  Status: Developing

=head1 ABSTRACT

Get rid of it completely.

=head1 DESCRIPTION

dump is a common subroutine name.  People often try to define a dump
subroutine and then get puzzled by the dump.  They have to name their
dump functions 'Dump' or 'dumper' and then they get annoying errors
when they call dump instead by mistake.

dump is not very useful anyway; see MIGRATION below.

=head1 IMPLEMENTATION

None needed.

=head1 MIGRATION

The translator should translate calls to dump() to 

kill 6 = $$;

instead.   

If the translator fails on dump LABEL, that is probably all right.
But if not, then it can translate

...
dump LABEL;
...

LABEL: 
...

to 

...
${^Please_Dump} = 1;
goto LABEL;
...

LABEL:
kill 6 = $$ if ${^Please_Dump};
undef ${^Please_Dump};
...
