+   ++  API one-line report format for dying/warning
++  +   MOD multiline like
+   ++  MOD port Test::Differences to refute
+   ++  TST Even more examples
++  ++  API todo() or $TODO - don't slow down passing tests!
++  ++  MOD Round-trip assertion
++  ++  MOD Util::Tempfile - preserve file if tests fail
+++ +   API If contract with args fails, display args
+++ +   API Optional short-circuit on first failure
+++ +   API Some extra goodies to contract {...} like title
+++ +   API verbosity switch to include more/less info in report
+++ +   API bail_out() - can die for now, only needed for Unit
++  +++ DRV add Test-based driver
++  +++ MOD Provide what Test::Most can
++  +++ MOD import Test::Builder-based tests
+++ +++ DRV A TAP consumer class
+++ +++ DRV Own Unit-testing backend (adhere TAP::Harness)

# *Priority* _decreases_ from `+` to `+++`

The questions to ask oneself:

* Can 1.0 ship without this?
* Is not having this done awkward?
* Are there users asking for this?
* Do other features depend on this?

# *Complexity* _increases_ from `+` to `+++`

The questions to ask oneself:

* What is the simplest meaningful example?
* How should this be tested/documented?
* What extra knowledge is required for this?
* What other features does this depend upon?

# *Tag* is 3 uppercase letters

Known tags are (also used in commit messages):
