I have a question concerning Perl's closures.

The code below should, to me, completely work. But when I call doesnt_work @r is not initilized. 8( Which is surpising to me because perl knows that sub doesnt_work exists so why doesn't it init @r when it is called?

#!/usr/bin/perl -w
{       my @s=("This works\n");
    sub works { shift @s}
}
#This works..
print &works;

# Error!!
# This gives an error of Use of uninitialized value in print at ....
print &doesnt_work;
{       my @r=("Should this work..\n");
    sub doesnt_work{ pop @r;    }
}
