devel/p5-failures 0.004 FreeBSD

This module lets you define an exception hierarchy quickly and simply.

Here were my design goals:

• minimalist interface
• 80% of features in 20% of lines of code
• depend only on core modules (nearly achieved)
• support hierarchical error types
• identify errors types by name (class) not by parsing strings
• leave (possibly expensive) trace decisions to the thrower

Currently, failures is implemented in under 70 lines of code.

Failure objects are implemented with Class::Tiny to allow easy subclassing (see custom::failures), but Class::Tiny only requires core modules, so other than that exception, the 'core only' goal is achieved.
