      Description

      select column_list(column_create('a', 'val1'));
      # +-----------------------------------------+
      # | column_list(column_create('a', 'val1')) |
      # +-----------------------------------------+
      # |                                         |
      # +-----------------------------------------+
      # 1 row in set (0.00 sec)
      
      select length(column_list(column_create('a', 'val1')));
      # +-------------------------------------------------+
      # | length(column_list(column_create('a', 'val1'))) |
      # +-------------------------------------------------+
      # |                                               0 |
      # +-------------------------------------------------+
      # 1 row in set (0.00 sec)
      
      

      For numeric identifiers seems to work all right:

      select column_list(column_create(1, 'val1'));
      
      # +---------------------------------------+
      # | column_list(column_create(1, 'val1')) |
      # +---------------------------------------+
      # | `1`                                   |
      # +---------------------------------------+
      # 1 row in set (0.00 sec)
      
      select length(column_list(column_create(1, 'val1')));
      # +-----------------------------------------------+
      # | length(column_list(column_create(1, 'val1'))) |
      # +-----------------------------------------------+
      # |                                             3 |
      # +-----------------------------------------------+
      # 1 row in set (0.00 sec)
