    Thanks for taking this big issue. It must be helpful for Curator's users. 
Do you think that this change must be done with source-level compatibility? If 
the answer is positive, it looks good to me.
    
    > However, this won't be a problem because there's no reason to think that 
Guava will change or remove these basic interfaces.
    
    It's realistic decision, especially for Function and Predicate interfaces. 
About 
[TypeToken](https://google.github.io/guava/releases/snapshot/api/docs/com/google/common/reflect/TypeToken.html),
 however, it is marked with [Beta 
annotation](https://google.github.io/guava/releases/snapshot/api/docs/com/google/common/annotations/Beta.html).
 Hence, I think the interface can be changed.

> The critical portion copied here:
> {quote}
> The problem classes that I have found are:
> * curator-framework: org.apache.curator.framework.listen.ListenerContainer : 
> method forEach takes a parameter of type com.google.common.base.Function
> * curator-framework: 
> org.apache.curator.framework.api.transaction.CuratorTransactionResult : 
> method ofTypeAndPath returns com.google.common.base.Predicate
> * curator-x-discovery-server: 
> org.apache.curator.x.discovery.server.contexts.GenericDiscoveryContext : 
> constructor takes param of type com.google.common.reflect.TypeToken
> * curator-x-discovery: org.apache.curator.x.discovery.InstanceFilter : 
> inherits from com.google.common.base.Predicate
> {quote}
> In the ensuing discussion, it sounded like we'd need to get started on an 
> implementation before we had enough information to determine whether the 
> changes are too intrusive or not.
