Test::Builder2::Types is not directly tested. Even though it's an internal use module, it's important and should be tested.
Write tests for it. You can use t/Test/int.t as a cheat sheet.
Add a test for Test::Builder2::Positive_Int.
Added tests for TB2::LC_AlphaNumUS_Str (#176)
Added numbers to regex for LC_AlphaNumUS_Str
Fixed typo of LC_AlphaNumUs_Str
