Debug.Subject

Description

This is a probe subject which you can send in somewhere to get probed (not to be confused with a probe object, which does some active probing). All calls to LFUNs will be printed to stderr. It is possible to name the subject by passing a string as the first and only argument when creating the subject object.

Example

> object s = Debug.Subject();
 create()
 > random(s);
 _random()
 (1) Result: 0
 > abs(s);
 `<(0)
 _sprintf(79, ([ "indent":2 ]))
 (2) Result: Debug.Subject
 > abs(class { inherit Debug.Subject; int `<(mixed ... args) { return 1; } }());
 create()
 `-()
 destroy()
 (3) Result: 0
 > pow(s,2);
 `[]("pow")
