- Defined in namespace Smalltalk
- Category: Language-Data types
- I pretend to store my value in a variable, but I don't actually.
You can use the only instance of my class (returned by `ValueHolder null')
if you're not interested in a value that is returned as described in
ValueHolder's comment.

- value
- Retrive the value of the receiver. Always answer nil
