Nested array comparisons

[dunbarx at aol.com]

Hi.


I thought if you refer to an array the way you did, you would always get "empty" for each, and that would always be a false positive.  I always thought, at the array variable level, evaluation comes to nothing at all.


So I would have thought you would have to combine the arrays first, and then compare them, after they are no longer array variables, but rather ordinary ones. I assume that it makes no difference what you use as the delimiters, since you will not be working with the array data, just comparing them.

If one has two nested arrays, can you compare the two for equality by doing

if deepArray_1 is deepArray_2 then
   -- do whatever
end if

It looks like this does not work. That is, you get false positives at times when 
the two arrays are in fact not equal. Can not find documentation to determine 
whether this is bug of the expected behavior!
