1. This certainly seems like the expected behavior (didn't look for documentation). The aliasing tricks happen with arrays and scalars as well. Why shouldn't it work with hashes in a list context? As for the keys not changing, I wouldn't expect them to since this would mean the key would need to be rehashed and possibly moved to a different bucket. It's easier to just make it unmodifiable.
  2. Wouldn't you expect the same behavior if you just used $h{'a'} or @h{qw(a c e)}?
  3. It'd surprise the hell out of me if it didn't behave this way.
