use has it's own scope?

Hi in the following code does the declaration of $y happen in a different scope.

Is it documented behaviour?

t_set.pl

use strict;
use warnings;
use B::Deparse;

sub test {
   use set my $y =666;
   print $y;
}

#test();

print B::Deparse->new()->coderef2text(\&test);

error

Global symbol "$y" requires explicit package name at d:/exp/t_set.pl a
+borted due to compilation errors.
["set", 666]

set.pm

exec 't_set.pl' unless caller;

package set;
use strict;
use warnings;
use Data::Dump qw/dd pp/;



sub import {
   dd \@_;
}
1;

use docs say "It is exactly equivalent to BEGIN { require Module; Module->import( LIST ); }" so probably yes LIST has its own scope.

Thanks for RTFM for me! ;)

FYI I wondered if B::Deparse could show this. The answer is yes, with level 5 of deparsing or higher, use statments will be translated into their equivalent BEGIN blocks:

perl -MO=Deparse,-x5 -e "use Set my $x = 12;"
sub BEGIN {
    require Set;
    do {
        'Set'->import(my $x = 12)
    };
}
-e syntax OK

I don't think the fact that the lexical has a scope even shorter than the BEGIN block changes anything though.
