There are no array slices in your examples. In a [] subscript,
expressions are evaluated in scalar context.

Yes, this gives the subscript 1. Not a bug.

That's a flip-flop, not a range, due to scalar context.
It's consistent with this :
$ perl -le 'print $a while $a = 0..1' | head
1
2
3
4
5
6
7
8
9
10
but I don't explain this behaviour, since 0 should be false.
Might be a bug.

An array in scalar context gives length, so the subscript here is 2. Not
a bug.
