Before setting the value, a check is made on the type constraint of
the attribute, if it has one, to see if the value passes it. If the
-value fails to pass, the set operation dies with a L</throw_error>.
+value fails to pass, the set operation dies.
Any coercion to convert values is done before checking the type constraint.
To check a value against a type constraint before setting it, fetch the
attribute instance using L<Class::MOP::Class/find_attribute_by_name>,
fetch the type_constraint from the attribute using L<Moose::Meta::Attribute/type_constraint>
-and call L<Moose::Meta::TypeConstraint/check>. See L<Moose::Cookbook::Basics::Recipe4>
+and call L<Moose::Meta::TypeConstraint/check>. See L<Moose::Cookbook::Basics::Company_Subtypes>
