** (BSON Type) - 
** Wraps a JavaScript function and its arguments.
** 
** 'Code' is not 'const' because the 'scope' document *could* contain `Binary` data. 
@Serializable
class Code {
    
    ** JavaScript code.
    Str code
    
    ** A mapping from identifiers to values, representing the scope in which the code should be 
    ** evaluated. Essentially a map of method parameters and their arguments.
    Str:Obj? scope
  
    ** Creates a BSON Code instance.
