[Oz] Multiple evaluation question

[Tobias Mueller]

Hello Kent,

you can write a procedure (actually a function but this is not important
here) and then apply this procedure to different items:

proc {Test Item R}
   R = (Item.attr1 \=: Item.attr2)
end

You can use this procedure and Map to reflect the validity of your
constraint of a list of items:

ItemsList = [item(attr1:1 attr2:2) ... item(attr1:1 attr2:1)] 
Rs = {Map ItemsList Test}
=> Rs = [1 ... 0]

Hope that answers your question.

Regards
-- Tobias
