The proposed syntax contributes to readability because it reduces redundancy and
tells us that a key has the same name as the corresponding variable.

For example, it is obvious that only name has a different name from
the corresponding variable in the following code:

    h = {
      name: username,
      password,
      e_mail
    }

Why not support ECMAScript6-like hash literals?

For example,

    {x, y}

is equivalent to:

    {x: x, y: y}

For convenience, the prefix of global, instance, and class variables should be removed from the key name as follows:

    a = 1
    B = 2
    $c = 3
    @d = 4
    @@e = 5
    p({a, B, $c, @d, @@e, f: 6})
    #=> {:a=>1, :B=>2, :c=>3, :d=>4, :e=>5, :f=>6}
