[kepler-dev] Question about OrderedRecordToken

[Edward A. Lee]

Ben,

I have a question about ordered record tokens.
In the expression evaluator, I can do:

 >> a = [x = 1, y = 2]
[x = 1, y = 2]

 >> c = [y = 2, x = 3]
[y = 2, x = 3]

 >> a + c
[y = 4, x = 4]

 >> c + a
[y = 4, x = 4]


What determines the order in the result?

Also, if I do:

 >> a.getType()
object({x = int, y = int})

This description of the type seems exactly the same as
the description I get from an (unordered) record token.
Is this a problem? (I don't really know...)

Thanks!
Edward
