I am not that familiar with the processing phases BEGIN,INIT,END, that's why I asked. Is there a way to call the method at the END of execution of the caller?

END time is the same for all, so yes, that works: 

# file CallMe.pm
package CallMe;
use 5.010;
use strict;
use warnings;

my @to_call;

sub import {
    my ($self, @routines) = @_;
    my $call_package = (caller(1))[0];
    push @to_call, $call_package. "::$_" for @routines;
}

END {
    no strict 'refs';
    $_->() for @to_call;
}

1;

And then in your script: 

use 5.010;
use lib '.';
use CallMe 'foo';

sub foo { say 42 }
say 'in mainline';

prints 

in mainline
42
