I'm developing a package that can be used with tied variables, but can't seem to make autoloading work on the tie routines (TIEWHATSIT, FETCH, STORE...).

As long as I keep these routines ahead of the __END__ statement my tests work well, but when I put them after, perl complains that it can't find them. My package contains the following AUTOLOAD routine:
our $AUTOLOAD;
sub AUTOLOAD {
    # this is used to 'autoload' constants from the constant()
    # XS function.  If a constant is not found then control is passed
    # to the AUTOLOAD in AutoLoader.

    my $constname;
    ($constname = $AUTOLOAD) =~ s/.*:://;
    croak "& not defined" if $constname eq 'constant';
    my $val = constant($constname, @_ ? $_[0] : 0);
    
    if ($! != 0) {
        if ($! =~ /Invalid/ || $!{EINVAL}) {
            $AutoLoader::AUTOLOAD = $AUTOLOAD;
            goto &AutoLoader::AUTOLOAD;
        } else {
            croak "Your vendor has not defined MMA macro $constname";
    }   }
    eval "sub $AUTOLOAD { $val }";
    goto &$AUTOLOAD;
}

Also things seem to work the same whether there's a require AutoLoader or use AutoLoader near the start of my package.

The routine above is slightly different than the one shown on the perl.org Autoloader page. When I tried to edit mine to be exactly like the one on the perl.org page, big trouble broke loose, with complaints about constants not being allowed to be used under strict (and such). Of course I may have edited the routine imperfectly.

My Makefile.PL file uses ExtUtils::MakeMaker, and the right things seem to happen during make, like splitting into the right .al files.

Is there anything incompatible between tie subroutines and autoloading? If not, how should I proceed toward making autoloading work?
