content ← liftIO $ hGetContents hFile return content
These two lines can be replaced by the shorter
liftIO $ hGetContents hFile
You are right and I knew this before. This was the from movie "The imperative return strikes again!"
Somehow I understand but I don't have the feeling yet why I apply ErrorT to the whole catched expression instead of liftIO. Do you have a nice explanation for it?
Hm, not sure whether I can come up with something nice.
... I think I understood at least part of it. When I read it it does make sense but I have to polish my monadic skills before I get to actually feel it. Thanks a million for the effort of explaining it! ovidiu
