Example

use lang\reflection\Invocable;

$reflect= new Invocable(/** Handle */ fn(string $name): string => '@'.strtolower($name));
$reflect->name();              // null for anonymous functions like above
$reflect->comment();           // "Handle"
$reflect->annotations();       // lang.reflection.Annotations
$reflect->annotation($type);   // ?lang.reflection.Annotation
$reflect->parameters();        // lang.reflection.Parameters(size: 1)
$reflect->parameter(0);        // lang.reflection.Parameter(name: "name")
$reflect->parameter('name');   // -"-
$reflect->returns();           // lang.reflection.Constraint(type: 'string', present: true)
$reflect->invoke(['Test']);    // "@test"

Note: Annotations are only supported in PHP 8.0+!

Questions

• Should this class be named Invocable instead? It matches the invoke() method and describes what the class reflects, whatever syntax created the value. Its only drawback is that it sounds a bit like an interface name.
• Should we have $closure->invoke($bind, ['Test']) to match Routine::invoke()?
