ECMAScript

Here is an equivalent example in ECMAScript, and therefore works in JavaScript and ActionScript:

// Without reflection
new Foo().hello()
 
// With reflection
 
// assuming that Foo resides in this
new this['Foo']()['hello']()
 
// or without assumption
new (eval('Foo'))()['hello']()

Common Lisp

Here is an equivalent example in Common Lisp:

;;Without reflection
(hello)
 
;;With reflection
(funcall (find-symbol "HELLO"))
