Extension 'failure_message' system is clunky #27

Closed lgrozinger closed 5 years ago

lgrozinger commented 5 years ago

Probably better to have an ExtensionError that extensions can raise and authors can subclass.

Extensions should now be written to raise ExtensionError upon failure.

Work still to do on this is to make env.interpret() handle these exceptions in a sensible way.
