syntax

Ok, so I was comparing some stuff in my own DSL to Ruby. One construct they both support is this

x=["key" => "value"]

Knowing the difference between arrays and hashes, I would think this to be illegal, but the result in Ruby is

[{"key" => "value"}]

Why is this? And with this kinda syntax why can't you do

x=("key" => "value")

Why is an array a special case for implicitly created hashes?
