This role makes use of Type::Tie to add type-checking behavior to
The first argument passed to the constructor should be a Type::Tiny type
(or other object conforming to Type::API, as of v2.25):
use Types::Standard -all;
my $arr = hash_of ArrayRef() => (foo => , bar => );
Values are checked against the specified type when the object is constructed
or new elements are added.
If the initial type-check fails, a coercion is attempted.
Values that cannot be coerced will throw an exception.
