Type library kura meets built-in class.

#perl

https://metacpan.org/pod/kura

The type library kura now possible to use the Perl with built-in class. This allows you to gather objects and types.

use v5.40; use experimental 'class'; class Fruit { use Exporter 'import'; use Types::Common -types; # kura meets built-in class! use kura Name => StrLength[1, 255]; field $name :param :reader; ADJUST { Name->assert_valid($name); } } my $fruit = Fruit->new(name => ''); # Error!
Enter fullscreen mode Exit fullscreen mode

This is a unique feature of kura, that isn't possible with Type::Library.

Feel free to give it a try!
