I've just finished doing some XSUB work, following along with the perlxstut manpage. After finishing, I attempted to add the named of some of the functions from the xs code to "all" EXPORT_TAG of the module. This does not seem to work. So if my xsub defined procedures a, b, and c neither adding qw(a b c) or qw(&a &b &c) seems to have any effect.

I have noticed that the h2xs-generated code contains a comment that says "Preloaded methods go here", but neither the perlxs or perlxstut talks about "preloading" - does this have anything to do with it?

Code below (with stuff renamed slightly).

Thanks, --------- 
package toolong::totypeeverytime;

use 5.008005;
use strict;
use warnings;
use Carp;

require Exporter;
use AutoLoader;

our @ISA = qw(Exporter);

# Items to export into callers namespace by default. Note: do not expo
+rt
# names by default without a very good reason. Use EXPORT_OK instead.
# Do not simply export all your public functions/methods/constants.

# This allows declaration        use foo ':all';
# If you do not need this, moving things directly into @EXPORT or @EXP
+ORT_OK
# will save memory.
our %EXPORT_TAGS = ( 'all' => [ qw(
a b c
) ] );

our @EXPORT_OK = ( @{ $EXPORT_TAGS{'all'} } );
our @EXPORT = qw(

);

our $VERSION = '0.01';

require XSLoader;
XSLoader::load('foo', $VERSION);

# Preloaded methods go here.
