While Class::Method::Modifiers is primarily meant to wrap methods, it can also be used to wrap functions. Functions may have prototypes, so it would be better if they could maintained in the wrapper. This works similarly to the lvalue attribute. If a before or after is applied, the wrapper takes its prototype from the sub being wrapped. If an around is applied, the modifier sub's prototype is used. This is rather strange for arounds, as the parameters it is passed will still include the wrapped sub as the first parameter, so the parameters won't match the prototype exactly. Even with that oddness, it still seems to be the best option. This also means an around could change the prototype, which will throw warnings.

Since I created my PR, Test::Fatal and Test::Warnings were intentionally dropped as prereqs, so we don't want to reintroduce them. I've rebased my PR #6, updating it to avoid Test::Fatal and Test::Warnings, and integrating the additional testing you wrote here (but also updated to avoid Test::Warnings). Thanks. |

This is a
