> When writing threat triage rules I would like the score for a rule to be determined by a stellar statement, rather than a fixed number triggered by a boolean stellar statement.
> For example: 
> {code}
> "triageConfig" : {
>  "riskLevelRules" : [
>    {
>      "name" : "Abnormal Value",
>      "comment" : "FORMAT('For %s; the value %s exceeds threshold of %d',
> hostname, value, value_threshold)"
>      "rule" : "SOME_STELLAR_FUNCTION(value) > value_threshold",
>      "score" : "SOME_STELLAR_FUNCTION(value)"
>    }
>  ],
>  "aggregator" : "MAX"
> }
> {code}
> Note that in this scenario it would also be beneficial to cache part of the statement to avoid likely duplication between rule and score evaluation.
