I was thinking of something else, but on second thought I don't think it is
valid.
> Conditionals as map keys do not function in Stellar
> ---------------------------------------------------
>
> Key: METRON-1254
> URL: https://issues.apache.org/jira/browse/METRON-1254
> Project: Metron
> Issue Type: Bug
> Reporter: Casey Stella
>
> We currently cannot represent map literals in stellar where the keys are
> conditionals. For instance, the expression { x < 10 : 'info' } cannot be
> parsed currently and it should do. Having this enables a switch-style
> statement: MAP_GET(true, { x < 10 : 'info', x >= 10 : 'warn' })
