Ruby's 'principle of least surprise' strikes me again. From the docs:
Equality— Two hashes are equal if they each contain the same number of keys and if each key-value pair is equal to (according to
Object#==) the corresponding elements in the other hash.
An example:
hash = { 7 => 35, "c" => 2, "a" => 1 }
doppelganger = { "a" => 1, "c" => 2, 7 => 35 }
hash == doppelganger #=> true
