It gets parsed as:

SOMETHING = [ 2355, (SOMETHING2 = 3453) ]

Because of how multiple assignment and destructuring work, the RHS will be
treated like an array

a = 1, 2 # => [1, 2]

Now this particular assignment has an assignment in the RHS, which is
treated like this.
SOMETHING = 2355, SOMETHING2 = 3453
SOMETHING = 2355, (SOMETHING2 = 3453)
SOMETHING = 2355, 3453

For correct multiple assignment, it would be
SOMETHING, SOMETHING2 = 2355, 3453
