24 Hash::Diff returns the difference between two hashes as a hash.
25
26 diff ( <hashref>, <hashref> )
27 Diffs two hashes. Returns a reference to the new hash.
28
29 left_diff ( <hashref>, <hashref> )
30 Returns the values in the left hash that is not, or different from
31 the right hash.
32
34 This will not handle self-referencing/recursion within hashes well.
35 This will only handle HASH and SCALAR.
36
37 Plans for a future version include incorporate deep recursion
38 protection. And support for ARRAY.
