This is a trivial OO wrapper implementing the concept called a dispatch table (ie. subrefs in a hash). All of its methods are direct equivalents to a single statement manipulation of a hash, so it hides the intent of trivial code behind an API. You donâ€™t get any added simplicity for that obscurity, but you do get an extra dependency.
The module name is horribly chosen: I certainly wouldnâ€™t think to use â€œchestâ€ as a keyword when searching CPAN for something like this â€“ assuming I ever felt the need for an OO dispatch table in the first place. It also opens a new top-level namespaceâ€¦ why it needed to, Iâ€™m not sure.
At least it has decent docs and a superficial few actual tests.
To make an unnecessarily long story short: stay away.
