I'll bite.
Please, don't.
So what do you expect: take 5 [1,2,3,4,5,undefined] to do?
Nothing! It's a value, not an instruction!
So it does seem to matter how much of the list it evaluates...
No, it's implementation details. I'm reasoning about values, not computations, and I use complete orders for reasoning. What really matters is that implementation gives me results that agree with this reasoning - until we consider performance issues.
Well, that depends of your notion of interesting. I defined it - I'm interested in things that are observationally equivalent.
That's your choice, and I certainly can't argue, but I can't help mentioning that this is a bit weird.
