in thread namespace craziness

$x was declared with my, so it is a lexical variable and not in any namespace/package. The package declarations are really a red herring in this code. Compare these similar scripts: 
#!/usr/bin/perl -w

use strict;

use constant FIRST => 25;

my $x = FIRST;

use constant SECOND => defined $x ? FIRST : 2;

print SECOND * $x, "\n";

__END__

#!/usr/bin/perl -w

use strict;

use constant FIRST => 25;

my $x ;

BEGIN { $x = FIRST; }

use constant SECOND => defined $x ? FIRST : 2;

print SECOND * $x, "\n";

__END__
