perl - 禁止 Moose 类中的非属性参数

Question

如果 Moose 的构造函数调用中有额外的参数不是属性，有没有办法死？例如，这个:

package Shoe;
use Moose;
has 'size'  => (is => 'ro', isa => 'Num');
has 'color' => (is => 'ro', isa => 'Str', default => 'brown');
1;

会死在

my $sneaker = Shoe->new(size => 11, colour => 'white');

因为 colour不是 Shoe 的属性.

我可以发誓我已经看到了一个模块或其他东西可以做到这一点，但我找不到它。

Answer 1

对我来说作品MooseX::StrictConstructor :

package Shoe;
use Moose;
use MooseX::StrictConstructor; # <-- that's all what need
has 'size'  => (is => 'ro', isa => 'Num');
has 'color' => (is => 'ro', isa => 'Str');
1;

package main;
my $sneaker = Shoe->new(size => 11, colour => 'white'); #blows up
