in reply to Automatically add all defined functions to your @EXPORT

To pick up declared but not defined subs, use exists &$_ instead. Also, avoid all-uppercase names.* Example: 
package Foo;
use strict;
use warnings;
our @EXPORT = do {
  no strict 'refs';
  grep exists &$_ && /[a-z]/, keys %{ __PACKAGE__ . '::'};
};
sub bar;
sub AUTOLOAD {
   our $AUTOLOAD;
   print "AUTOLOADing $AUTOLOAD\n";
}
1;

*perlsub says:
Subroutines whose names are in all upper case are reserved to the Perl core, as are modules whose names are in all lower case. A subroutine in all capitals is a loosely-held convention meaning it will be called indirectly by the run-time system itself, usually due to a triggered event. Subroutines that do special, pre-defined things include AUTOLOAD, CLONE, DESTROY plus all functions mentioned in perltie and PerlIO::via.

Update: changed [_a-z] to [a-z], based on the new CLONE_SKIP method; but perhaps that ought to be CLONESKIP...
