One thing I don't like about the behavior with Hash transformed to Array is that you can't use it to "normalize" argument to an array (for example to get an API which allows passing both array of hashes and singe hash) so you have to resort to something like `[arg].flatten`.

They differ in the nil case:

>> RUBY_DESCRIPTION # => "ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-linux]"
>> [*nil] # => [nil]
>> Array(nil) # => []

Indeed. I personally feel that Array() is more intent-revealing, but [*] is certainly an alternative.

You can use [*items] as well to do the same thing as Array(). I don't know if there are any reasons to use one over the other, but it's an option.
