[Hat] Tracing a program that uses Control.Monad.ST

Hi all, I am attempting to trace a program (Djinn) that uses library modules that are not supported by Hat, such as Control.Monad.ST . I was planning to add them to either add them to Hat before building or directly to the program itself. However, I fear that this and other modules were left out because there was some fundamental limitation of Hat when dealing with these. I don't want to discover this after hours of trying so I decided to ask here :). Cheers, Alexey P.S. Please cc me, I am not subscribed.
