I feel like you and Walter are both saying the same thing.

fromISOString sounds to me like a data validation function. It is 
one that once validated provides a "validated" type, much like 
SortedRange.

I don't think Walter disagrees with that, but isn't calling it 
out specifically. Did I get that right?
