Hello all. I am trying to lock a hash that is wihtin another hash, when using another hash, within a sub & I am getting the error above. Code is: 
use strict;
use threads;
use threads::shared;
use warnings;
sub lockit($) {
    my $uber_hashRef = shift ;
    print "Yey\n" if is_shared( $$uber_hashRef{'%y'} ) ;
    lock ($$uber_hashRef{'%y'}) ;
}
sub genSharedLower($) {
    my $hashRef = shift ;
    $$hashRef{'%y'} = &share({}) ;
}
my %all_shary_for_subs : shared ;
genSharedLower(\%all_shary_for_subs);
print "Yey\n" if is_shared( $all_shary_for_subs{'%y'});
lockit( \%all_shary_for_subs) ;

Output is:

Yey
Yey
lock can only be used on shared values at shared_issue.pl line 8.

How is the value that was acknoledged as shared in line 7 be unshared in line 8?
Thanks!
