Can you show us the code that doesn't fail, because 
package Person;
use Moose;
use Moose::Util::TypeConstraints;
enum Gender => qw(female male);
has sex     => ( is => 'rw', isa => 'Gender' );

package main;
my $M = Person->new( sex => '' ); # fails
#$M->sex( 'please' ); # fails

[download]

both fail for me (Uncaught exception from user code: Attribute (sex) does not pass the type constraint because: Validation failed for 'Gender' failed).

Update:

$ perl -MMoose -E 'say $Moose::VERSION'
0.44
$ perl -MMoose::Util::TypeConstraints -E 'say $Moose::Util::TypeConstr
+aints::VERSION'
0.22
$ perl -v

This is perl, v5.10.0 built for x86_64-linux-gnu-thread-multi

Unless I state otherwise, all my code runs with strict and warnings
