perl-Return-Value

Polymorphic return values are a horrible idea, but this library was written
based on the notion that they were useful. Often, we just want to know if
something worked or not. Other times, we'd like to know what the error text
was. Still others, we may want to know what the error code was, and what
the error properties were. We don't want to handle objects or data
structures for every single return value, but we do want to check error
conditions in our code because that's what good programmers do.
When functions are successful they may return true, or perhaps some useful
data. In the quest to provide consistent return values, this gets confusing
between complex, informational errors and successful return values.
This module provides these features with a simplistic API that should get
you what you're looking for in each context a return value is used in.
