Hi everyone. I'm looking for something specific. I'm trying to figure out how to use the depthFunc StateVar and I can't find any official documentation for it. I did a ":t depthFunc" in ghci and got "depthFunc :: StateVar (Maybe ComparisonFunction)" so I looked up ComparisonFunction and couldn't find anything official on that either. Is there any documentation for it? Maybe I wasn't looking in the right places? Thanks in advance. -Eitan
