Let (
  [
    ~field = field;
    ~fn = Case (
      not EvaluationError ( GetFieldName ( ~field ) ) ;
        GetFieldName ( ~field ) ;
      not EvaluationError ( GetField ( field ) ) or EvaluationError ( Evaluate ( field ) ) = 103 ;
        ~field
    )
  ];

  If ( not IsEmpty ( ~fn ) ; Quote( GetValue ( Substitute ( ~fn ; "::" ; "¶" ) ; 1 ) ) )
)

Can pass in a dynamically created field name or a reference with or without the table name included. Very helpful for when field names can change.
