Just help me understand: Where does the difference appear between a 'long'
member and a 'long?' member? (I understand we're using Nullable<> to represent
IDL's nullable or a missing value. Then it seems to me that there is no
difference in implementation between nullable types and not-nullable types.)

[bashi, 2014/07/29 11:51:21]

From the spec's viewpoint or the implementation's viewpoint?

Speaking of the spec, I can't figure out why nullable is needed, given that 'not
specified' and 'null' would mean the same thing in dictionaries, IIUC.

In the terms of our implementation, there should be no difference, as you
described. Nullable is supported because the spec says it is allowed (and easy
to implement).

Makes sense, thanks for the clarification!
