This is rather non-standard and also breaks the test, cf.

http://isabelle.in.tum.de/reports/Isabelle/report/d6e6227d86634c02890a3e60e508abc3

(Tests are run without quick_and_dirty, and rightfully so.)

lemma "False" sorry is indeed a strange kind of markup... I remember 
that the code generator has a notion of different "targets" (e.g., SML, 
Haskell, Eval,...). @Florian: Is it imaginable to add such unsound setup 
in a way that it does not infect the evaluation oracle by default?
