Sorry to disappoint you, but this would not work for two reasons:

1. Unpack ignores hash-part keys of the table.
2. More important, unpack(t1) == unpack(t2) compares only first
elements of the tables. It is equivalent to t1[1] == t2[1]. There is
no multi-argument equality operator, only assignment one.
