Re^5: If you believe in Lists in Scalar Context, Clap your Handsby ikegami (Pope)

How do you reconcile that with the fact that both the array and the array slice perform exactly the same action in list context: they put their members on the stack. Either they both make a list or neither does.
I bolded the mistake. Just like the right-hand ** doesn't return 3 in 2**3**4, The right-hand assignment doesn't return ($a, $b) in $r = ($a, $b) = 0..11. A list assignment in scalar context returns the number of items it was given to assign. 12, in this case.
There are two different sort of value. Three even.
I wouldn't say it has integer context, because that would imply a parallel with scalar vs list context. Scalar and list context force operands to returns a scalar and a list respectively. Integer coercion doesn't force operands to returns an integer.
Let's look at an example. Given f() % 3, f() is executed in scalar context and in "integer context".
Your argument relies on the premise of a parallel between scalar context and integer coercion, but it's very clear there isn't one. The premise is false, so the argument is moot.
This isn't relevant, but I thought you'd be interested in an additional difference: some operators (such |, & and ^) behave differently based on whether they're given a string or an integer. Some operators behave differently based on the length of the list they are given, but you won't find an operator that can accept both a scalar and a list.
