I think we should use an interface `ILambda` similar to java's counterpart:
https://github.com/apache/tinkerpop/blob/3.2.7/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/util/function/Lambda.java#L33
`Lambda.Groovy()` and `Lambda.Python()` could return `ILambda` instances.
That way we can have a compile type check for methods like `Filter()`,
`Until()`, etc... to accept only `ILambda` instances.
