Hi, With Prelude.catch, I could write "catch () $ \_ -> return Nothing". But with Control.Exception.catch, I must specify a type for the "_". What should I do?
Use SomeException for the type, as it is the base of the exception hierarchy.
But it is usually recommended that you *don't* do this, as it even captures Ctrl-c invocations: http://www.haskell.org/ghc/docs/latest/html/libraries/base/Control-Exception... -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
