A callable constructor model represents the model of a Ceylon class constructor that you can invoke and inspect

## Callablity

As with `Function` you can also invoke a `CallableConstructor`, doing so instantiates an instance:

     shared class Foo {
         shared String name;
         shared new foo(String name) {
             this.name = name;
         }
     }

     void test() {
     Constructor<Foo,[String]> ctor = `Foo.foo`;
     // This will print: Stef
     print(ctor("Stef").name);

## Genericity

This class inherits `Generic` but a constructor in Ceylon cannot have a type parameters. For symmetry with `CallableConstructorDeclaration.apply()` the `Generic.typeArguments` and `Generic.typeArgumentList` refer to the type arguments of the constructor's class.

Attributes
`container` | Source Code `shared formal ClassModel<Type,Nothing>? container` The class containing this constructor; the type of instances produced by this constructor. Refines `Model.container` ultimately refines `Declared.container`
`declaration` | Source Code `shared formal CallableConstructorDeclaration declaration` This constructor's declaration. Refines `FunctionModel.declaration` ultimately refines `Declared.declaration`
`type` | Source Code `shared formal ClassModel<Type,Nothing> type` This function's return closed type. Refines `FunctionModel.type`
