                                      java.util.Optional<? extends CelFunctionResolver> lateBoundFunctionResolver,

                               throws CelEvaluationException
```
    Runs interpretation with the given activation which supplies name/value bindings with the ability to track and resolve unknown variables as they are encountered.
    This method allows for late-binding functions to be provided per-evaluation, which can be useful for binding functions which might have side-effects that are not observable to CEL directly such as recording telemetry or evaluation state in a more granular fashion than a more general evaluation listener might permit.
    
    Throws:
    
    CelEvaluationException
