Review Comment:
   At the end of the day this doesn't need to be the final solution.
   
   While `Pattern#where(FilterFunction)` is a lot more user-friendly this would 
be a breaking change, because an existing `SimpleCondition` would satisfy both 
signatures which the compiler rejects.
   I'd like to avoid using different method names for the `FilterFunction` 
variants.
   
   We could also modify `SimpleCondition` to not implement the `FilterFunction` 
interface, but this would again be a potentially breaking change.
