I am trying to understand the new exceptions package in base-4
Control.Exceptions. The documentation for catchJust is the same as in
Control.OldException including this example:
result <- catchJust errorCalls thing_to_try handler
Control.OldException provides the predicate errorCalls, but the new one
does not. I don't see how to write it.
Thanks for reading.
