BIG THANKS!! Import::Into works like a charm!!! It goes exactly I would expect and feel really transparent!

# X.pm
package X; 
sub new { bless{ Name=> "I am X"}, shift} 1;

#Y.pm
package Y;
require Exporter;
our @ISA =qw/Exporter/;
our @EXPORT_OK = qw/TestY/;

sub new {bless{ Name=> "I am Y"}, shift;}
sub TestY {print "@_ EXPORT_OK"}
1;

#MyStuffs.pm
package MyStuffs;
use Import::Into;

sub import {
    my $target = caller;
    X->import::into($target);
    Y->import::into($target, qw/TestY/);
}
1;

#main.pl
use MyStuffs;
use Data::Dumper;

my $x = new X;
my $y = new Y;

print "X dumps: ";
print Dumper $x;

print "$/$/Y dumps: ";
print Dumper $y;

print "$/$/";
TestY("I am");

print "$/";
Y::TestY ( "Still" ) ;

__END__

X dumps: $VAR1 = bless( {
                 'Name' => 'I am X'
               }, 'X' );


Y dumps: $VAR1 = bless( {
                 'Name' => 'I am Y'
               }, 'Y' );
