Yes, if the objective is to include special characters or facilitate
multi-lingual columns names and
it probably should be, then my suggestion is quite inadequate.
Perhaps there could be a simple name -> column number mapping in place
of _names. References
to a column, or a field in a record, could then be through this dictionary.
Basic access to data in a record would be by position number, rather
than name, but the dictionary
would facilitate access by name.
Data could be referenced either through the column name: r1.c2 or
through the record r1.c2, with the possibility that the index is
multi-dimensional in either case.
