I still didn't manage to do it with Perl6::Export::Attrs (i'll try more - help appreciated - details at the end of this message).
But finally i managed to override the import() methods appropriately for the cases when Export is used. Simply overriding import() didn't work, as i lost the benefit of Export. I had to use the export_to_level() method (defined by Export) in the overriden import().
Here is the simple sample code (all files start with use strict and warnings). 

package Mod2;

require Exporter;
our @ISA = qw(Exporter);
our @EXPORT = qw(subr); # Exported by default

sub import { 
    print "import() was called with arguments : @_\n"; 

    my $my_arg = pop @_;
        # i have to pop(), 
        # because export_to_level() doesn't want to see $my_arg
    print "my arg: $my_arg\n";

    Mod2->export_to_level(1, @_);
}

sub subr { return "subr() was called\n"; }
1;

And the script to run it : 
use Mod2 'argument'; 
print subr();

[download]
Which displays : 
import() was called with arguments : Mod2 argument
my arg: argument
subr() was called

[download]
It works !

Now with Perl6::Export::Attrs, i tried this (with the same script, using Mod3 instead of Mod2; i also tried to not put any argument after use Mod3;) : 

package Mod3;

use Perl6::Export::Attrs;

sub subr :Export(:DEFAULT) { return "subr() was called\n"; }

IMPORT{ print "inside the IMPORT block\n"; }

1;

and obtained this output: 
inside the IMPORT block
Can't call method "IMPORT" without a package or object reference at Mo
+d3.pm line 11.
Compilation failed in require at Script3.pl line 5.
BEGIN failed--compilation aborted at Script3.pl line 5.

Does anyone know how to use this IMPORT block properly?
