Iterate over 2 lists in a closure?

[Les Hartzman]

Hi,

I want to know if it's possible to have a closure that can iterate over 2
equal length lists? The equivalent of doing list1.each, list2.each { ... },
where each list is a list of an user-defined type.

Basically I want to compare elements in the lists to see if they are equal.

Thanks.

Les
