/**
 * Exist for backward compatibility only; it has represented a macro or function declaration in the AST. The current
 * representation isn't a public class, but is {@code insteanceof} this for backward compatibility.
 * 
 * <p>
 * Historical note: This class exists for backward compatibility with 2.3. 2.4 has introduced {@link UnboundTemplate}-s,
 * thus, the definition of a callable and the runtime callable value has become to two different things:
 * {@link UnboundCallable} and {@link BoundCallable}. Both extends this class for backward compatibility.

 * @see UnboundCallable
 * @see BoundCallable
 * 
 * @deprecated Subject to be changed or renamed any time; no "stable" replacement exists yet.
