Cannot alias parent attr from child class?

[iynehz]

Is it possible to alias a parent class attr from child class? Below would give Found unknown argument 'alias' in the has declaration for 'foo' in class Bar.

use 5.020;
use warnings;

package Foo {
    use Moose;
    has foo => (is => 'ro');
}

package Bar {
    use Moose;
    use MooseX::Aliases;
    extends 'Foo';
    has '+foo' => (alias => 'baz');
}

my $bar = Bar->new( baz => 1);
say $bar->foo;
