The issue is not using the interface, I'll address that.
> Stellar Shell: Should have a way to validate deployed functions
> ---------------------------------------------------------------
>
> Key: METRON-1339
> URL: https://issues.apache.org/jira/browse/METRON-1339
> Project: Metron
> Issue Type: New Feature
> Reporter: Otto Fowler
> Assignee: Otto Fowler
>
> It is possible that the Stellar Language is changed during a release, meaning
> stellar expressions that are in zookeeper are now invalid, and will not run.
> Currently users cannot verify this without just letting them fail and hunting
> the errors down.
> The Stellar Shell should expose a '%' function that will verify that all
> stellar functions compile and are syntactically correct.
