A way of running any IO type and capturing any exception, maybe, I think...

Async IO Either

This is a tiny package that captures a pattern I've been using a lot...

Essentially I am tired of needing something of (IO a) and it so often coming with exceptions that are not indicated in the type. Generally speaking my application, like many others, is just going to throw in the towel when an exception occurs, but I would prefer it if a value was provided. This would then allow me to decide just what sort of tantrum my application will throw.

I've tried to understand the different manners of handling exceptions in Haskell, and I'm sure there is a better or more fitting approach. But this is what I have for now.
