18       All exceptions thrown from within PPI will be instances or derivations
19       of this class.
20

METHODS

22   new $message | message => $message, ...
23       Constructs and returns a new "PPI::Exception" object.
24
25       A message for the exception can be passed, either as a string or as
26       "message => $message". The message is available via the "message"
27       method.
28
29   throw
30       If called on a "PPI::Exception" object, throws the object.  If called
31       on the class name, uses the arguments to construct a "PPI::Exception"
32       and then throw it.
33
34       Each time the object is thrown, information from the Perl <caller(0)>
35       call is saved and made available via the "callers" method.
36
37       This method never returns.
38
39   message
40       Returns the exception message passed to the object's constructor, or a
41       default message.
42
43   callers
44       Returns a listref, each element of which is a listref of caller(0)
45       information.  The returned listref can be empty.
