Inspect your exception before it kills you:
This packages defines an alternative error handling procedure
that can be used instead of the usual:
raise Exception end
This solves the problem that one often wants to
inspect an exception while also terminating the
program execution (but not the inspection process).
This main procedure error.raise
inspects an exception in an independent Oz process before
raising it as usual. It type is
value ->, i.e. it inputs an exception,
inspects and raises it. An example is provided
in the functor error/test.oz.
declare Modules = ['x-ozlib://niehren/error.ozf']
declare [Error] = {Link Modules}
declare Raise = Error.'raise'
declare Exception = error(msg :gargel
package:'your package'
file :'your file'
value :'your value')
{Raise Exception} {Inspect 'this will never be browsed'}
