21 This is a reasonably new internal component for Path::IsDev.
22
23 Its purpose is to communicate state between internal things, and give
24 some sort of introspectable context for why things happened in various
25 places without resorting to spamming debug everywhere.
26
27 Now instead of turning on debug, as long as you can get a result, you
28 can inspect and dump that result at the point you need it.

31 "BUILD"
32 "add_reason"
33 Call this method from a heuristic to record checking of the heuristic
34 and the relevant meta-data.
35
36 $result->add_reason( $heuristic, $matchvalue, $reason_summary, \%contextinfo );
37
38 For example:
39
40 sub Foo::matches {
41 my ( $self , $result_object ) = @_;
42 if ( $result_object->path->child('bar')->exists ) {
43 $result_object->add_reason( $self, 1, "child 'bar' exists" , {
44 child => 'bar',
45 'exists?' => 1,
46 child_path => $result_object->path->child('bar')
47 });
48 $result_object->result(1);
49 return 1;
50 }
51 return;
52 }
53
54 Note that here, $matchvalue should be the result of the relevant
55 matching logic, not the global impact.
56
57 For instance, "excludes" compositions should still add reasons of
58 "$matchvalue == 1", but they should not set
59 "$result_object->result(1)". ( In fact, setting "result" is the job of
60 the individual heuristic, not the matches that are folded into it )
