Since you are wanting to compare two mutable Array, just use the eqv operator, which will do everything you want in a terse and easy to understand manner.


No, look at the example I've been using. Two arrays (1, 2, [EMAIL PROTECTED]) and (1, 2, [EMAIL PROTECTED]) clearly have different (unevaluated) contents. "eqv" only tells me whether they have the same value (when @x and @y are evaluated). That's a different question -- yes, it's the more common question, but I think the comparison I want to make is just as reasonable as ===, except there's no easy way to do it.
