I don't see any similarity in design or inheritance between what you're trying to do and and the example you quote... I don't think the constructor is what lets it do that, are you sure that's the complete code? No external operator functions? Also: You can't cast one value into two values.

ATTRIBUTES
All attributes of this class are read-only.
required
Is this parameter required (true) or optional (false)?
sigil
The effective sigil ('$', '@' or '%') of this parameter.
type_constraints
Type: Parse::Method::Signatures::TypeConstraint
Predicate: has_type_constraints
Representation of the type constraint for this parameter. Most commonly you will just call "meta_type_constraint" and not access this
attribute directly.
default_value
Type: Str
Predicate: has_default_value
A string that should be eval'd or injected to get the default value for this parameter. For example:
$name = 'bar'
Would give a default_value of "'bar'".
constraints
Type: ArrayRef[Str]
Predicate: has_constraints
"where" constraints for this type. Each member of the array a the string (including enclosing braces) of the where constraint block.
param_traits
Type: ArrayRef[ Tupple[Str,Str] ]
Predicate: has_traits
Traits that this parameter is declared to have. For instance
$foo does coerce
would have a trait of
['does', 'coerce']
METHODS
to_string
meta_type_constraint
Get the Moose::Meta::TypeConstraint for this parameter. Check first that the type has a type constraint:
$tc = $param->meta_type_constraint if $param->has_type_constraints;
