A simple test follows:

Hello, world!

Now perform a hash assignment:

test23 Hello, world! hello all 1

Now update the assignment and repeat:

test23 Hello, world! hello all 1

Now reassign the list and repeat:

test23 Hello, world! hello all 1 Temporary Temporary Temporary

A test in the JSON notation:

test23 Hello, world! hello all 1 Temporary Temporary 42

Pathological case: zero item hash:

Hash of number literals:

2

Hash of constants only:

test23 67 hello all one

Hash of list literals:

1, 2 3, 4 5, 6 7, 8

Hash of hash literals:

2 4 6 8

List of hash literals:

2
4
6
8
