Careful with semantics here.  First off, using the last comment line as the
source for names might initially make sense, except when there are comments
within the data file.  I would suggest going for "last comment line before
the first line of data".  Second, sometimes the names come from an
un-commented first line, but comments are still used within the file

Just some food for thought.  I don't know if the current design is best or
