hook and expecting certain fixture instances are torn down within (very
unlikely and would have been unreliable anyway).
+- fix issue290 - there is preliminary support now for parametrizing
+ with repeated same values (sometimes useful to to test if calling
+ a second time works as with the first time).
- fix issue246 (again) fix finalizer order to be LIFO on independent fixtures
depending on a parametrized higher-than-function scoped fixture.
(fix quite some effort so please bear with the complexity of this sentence :)
