die and exit

Does die call exit when it's excuted?
If so,when I overwrote exit() function in my script,would die call this customized exit?

I gave a test,but didn't see die calling exit distinctly.

This works as I wanted:
use strict;
use warnings;

sub exit {
    print "test exit";
    exit;
}

&exit;


But this won't:
use strict;
use warnings;

sub exit {
    print "test exit";
    exit;
}

die;


Glad to hear any words from you.
