NAME

Tie::Moose::Forgiving - don't die at the mere mention of an unknown key

SYNOPSIS

tie my %bob, "Tie::Moose"->with_traits("Forgiving"), $bob;

DESCRIPTION

Tie::Moose is very happy to throw exceptions.

If, for example, you use a hash key that doesn't correspond to one of the object's attributes, it will croak. Even if you used exists!

This trait prevents read-only accesses from throwing due to unknown attributes.

use v5.14;

package Person {
	use Moose;
	has name => (
		is     => "rw",
		isa    => "Str",
	);
	has age => (
		is     => "rw",
		isa    => "Num",
		reader => "get_age",
		writer => "set_age",
	);
}

my $bob = Person->new(name => "Robert");

tie my %bob, "Tie::Moose"->with_traits("Forgiving"), $bob;

my $x = $bob{xyz};   # ok ($x is undef)
$bob{xyz} = $x;      # would croak
