The constructor’s job is to bring the object into a usable state. There are basically two schools of thought on this. One group favors two-stage construction. The constructor merely brings the object into a sleeper state in which it refuses to do any work. There’s an additional function that does the actual initialization. I’ve never … Read more
Swallowing exceptions is a dangerous practice because: It can cause the user to think something succeeded when it actually failed. It can put your application into states that you didn’t plan for. It complicates debugging, since it’s much harder to find out where the failure happened when you’re dealing with bizarre/broken behavior instead of a … Read more

Obviously this is one of those questions where the only real answer is “it depends.” The main thing it depends on is where your are catching the exception. In general libraries should be more conservative with catching exceptions whereas at the top level of your program (e.g. in your main method or in the top … Read more
A method should only catch an exception when it can handle it in some sensible way. Otherwise, pass it on up, in the hope that a method higher up the call stack can make sense of it. As others have noted, it is good practice to have an unhandled exception handler (with logging) at the … Read more
Try turning on warnings in ghci. This enables the compile time warnings you can get with ghc by passing -W, for example.
