Good point, I had forgotten about the Prelude catch.  I think I can go remove a bunch of ScopedTypedVariables now.

Note that Prelude.catch has been deprecated in favor of Control.Exception.catch. If you want to catch IOErrors you can either use ScopedTypedVariables or System.IO.Error.catchIOError.

Control.Exception.catch is not in haskell 98 or haskell 2010. It also requires pulling in some heavy extensions and actually has fundamentally different behavior than Prelude.catch. We definitely should not consider it a replacement. John
