Hi,
I repeat my unanswered question in hope to find here some help:

Unfortunately the package hgearman does not provide any test or example and I can't work it out for myself how should be combined connectGearman and submitJob to put a job to the gearman job server.

The result of connectGearman is:

ghci> conn <- connectGearman (B.pack "x") ("localhost"::HostName) (4730::Port)
ghci> :t conn
conn :: Either GearmanError GearmanClient

but submitJob uses private function submit which deals with StateT. So I can only guess the result of connectGearman should be wrapped into S.StateT GearmanClient IO without faintest idea how to do that.
