implicit object distinguishingIsabelleMLExceptionConverter extends IsabelleMLExceptionConverter
Preconfigured instance of IsabelleMLExceptionConverter.
For certain known kind of ML exceptions (such as TERM _ etc.), it returns subclasses of IsabelleMLException
(such as TermMLException).
It uses recognizeException to recognize the exception, see there for a list of all supported exceptions.
Use by importing it.
