Fixes test_non_parallel_assignment

* I learned about non-parallel assignments

[#65851404]
Fixes test_parallel_assignments

* Learned that assigning variables to an array
  will assign those variables to the elements in
  that array in order

[#65851404]
Fixes test_parallel_assignments_with_extra_values

* Learned that if there are less variables than
  the number of elements in an array, then the
  variables will be assigned to an equal number of
  elements. Extra elements will not be assigned.

[#65851404]
Fixes test_parallel_assignments_with_splat_operator

* Learned that if a variable has a splat operator
  in it, it will be assigned the elements from
  its equivalent counterpart in an array and
  forward AS an array

[#65851404]
Fixes test_parallel_assignments_with_too_few_variables

* Learned that if more variables are assigned to
  an array with less than equal elements, the
  variables that have no "counterpart" will have
  a value of 'nil'

[#65851404]
Fixes test_parallel_assignments_with_subarrays

* Learned that subarrays within arrays can be
  assigned to variables. Subarrays are elements.

[#65851404]
Fixes test_parallel_assignemnt_with_one_variable

* Learned that variable followed by a "," means
  that you're assigning a single variable the
  value of the first element of an array
* If that variable doesn't have a "," after it,
  then it will assign the whole array to that
  variable (tested it myself)

[#65851404]
Fixes test_swapping_with_parallel_assignment

* Learned that you can use parallel assignment to
  change the value of variables
