Here we're switching to combinators instead of dereference operator.
It turns out the dereference operator was being executed upon test
setup, meaning that we were only using a only single value for each of
the executions of the property tests! Really not good.
And on Windows, we instead get:
operator* is not allowed in this context
ff6af6fc68/src/gen/detail/GenerationHandler.cpp (L16C31-L16C71)
Now a few of the property tests fail, because we're generating cases
which haven't been exercised before.
