Another example of this issue can be found here: DanielaSfregola/random-data-generator#33
from scalacheck-shapeless.
Maybe we should stop shrinking when we find a singleton here. Something like this:
case Inl(h) =>
if (headSingletons.value().contains(h)) Stream.empty
else tailSingletons.value().toStream.map(Inr(_)) ++ headShrink.value.shrink(h).map(Inl(_))
case Inr(t) =>
if (tailSingletons.value().contains(t)) Stream.empty
else headSingletons.value().toStream.map(Inl(_)) ++ tailShrink.shrink.shrink(t).map(Inr(_))
