Add tests that test all permutations:

[xsawyerx]

Wow. This took a while. Mostly to figure out, then write it out cleanly. Plenty of copy pasting and search/replace with Vim.

Why? Because I didn't want to do it dynamically.

This tests several things:

• Various common non-ref values do not pass is_ref().
• All plain references must pass is_plain_ref().
• All plain references fail all of the isblessed* functions.
• Each plain reference only passes a test for its type.
• All blessed references must pass is_blessed_ref().
• All blessed references fail all of the isplain* functions.
• Each blessed reference only passes a test for its type.
• All references (plain or blessed) should pass the is_ref().

Things still to do:

• Only test the formatref is it's > 5.6. Gotta add that distinction.
• Get plan count to be based on the hashes - not that important.
• Once isany* variant comes in (now's the time), it should be added to the tests.

[xsawyerx]

This is not complete yet. I'm adding more things.

I want to have these tests so I could add star the move of Ref::Util to Ref::Util::XS with default pure-Perl implementation.

[xsawyerx]

Improved the tests. Ready to be merged, IMHO.

[xsawyerx]

Merged!
