Better way to "cron" or execute UDF every N minutes in TICKscript?

I’m currently using deadman to effectively cron a UDF to execute every 1 minute:

stream
  |from()
    .measurement('does_not_exist')
      |deadman(1.0, 1m)
        @doSomething()

Is there a better or more idiomatic way to accomplish this? There’s no data source that this UDF should be triggered by; it’s purely a recurring task. There are other ways I could make this run, of course, but I’d like to continue to follow the Kapacitor/TICKscript/UDF pattern of the overall application. My initial attempt that didn’t work was to run a batch query every 1 minute:

batch
  |query('''SELECT * FROM "database"."retention_policy"."measurement" LIMIT 1''')
    .every(1m)
  @doSomething()

That reads better to me, but didn’t seem to ever execute the UDF.

Any better ideas?
