This is not an exhaustive list of TODO items.
 
* Write a bunch of tests for the exception API
 
* (More?) tests for user defined subs!
 
* Define roles properly.
 
* Trawl through perlfunc to find which things autodie may apply to.
 
* Generate a good way to allow subroutines to register themselves
  with roles and message handlers, possibly defining their own
  exception handler to use.
 
* Provide an autodie mixin which at least provides expected autodie
  behaviours, even if someone wants to use their own exception class.
 
* Provide a nicer way to override message handlers.
 
* Finalise the exception interface.
 
* Write a huge amount of documentation.
 
* Write a huge amount of tests.
 
* Test the many varied forms of sysopen.
 
* Test fcntl.
 
* !!! We need a proper way to override exceptions from system!
 
* Make sure that all the internal subroutines in Fatal continue to
  work using their old wacky interfaces.
 
* Test open(my $fh, '|-') || exec().
 
* Consider what happens when import is called at run-time!
  (Both in 5.10 and 5.8, but especially 5.8)

* Reduce the number of lexical guards we need in our array.
  We should be able to combine these, or have a single guard
  that does the right thing.
 
* Think about padwalker integration.  This can give us really
  pretty errors!
 
* Catch require/do and remove any autodying subs upon entry.
  At the end of file, replace them.  This is a better solution
  to using leak-guards, which require more time and space at
  run-time.
