In particular, unless I greatly underestimate the relative difficulties of the software modifications that would be needed, the significance of any one-time cost difference for those changes is miniscule relative to that of the ongoing (but less tangible) costs of adopting an otherwise inferior solution. I acknowledge that commas, whitespace, and combinations of those as token separators all have merits, but from the perspective of CIF overall, I firmly believe that whitespace as the only list token separators remains the best solution. I withhold further technical commentary at this time, in the hope that it will be unnecessary.
