perl - Why is a 'use' statement executed first in a BEGIN block? -

-

when execute following code, can't locate somepackage.pm in @inc ....

begin {     die;     use somepackage; }

why use executed before die?

use somepackage equivalent 

begin { require somepackage; somepackage->import }

a begin code block executed possible, is, moment completely defined. second begin (which implied use) defined first, , executed first.
