As I continue to tweak performance on both packages, I'm going to need to release minor updates.
I've modified the Reflect package onMissingMethod() mixin to perform the positional to named parameter conversion before invoking the InvocationHandler's invokeMethod function. This allowed me to removed the ensureParameterNames() from the InvocationHandler and refactor as an interface.
This refactoring of course required a few code tweaks in the MockInvocationHandler and sample code since CF is now enforcing the interface.
Also in Reflect, the Injectors are all placed in an array and processed with the same function. Less code this way, and it will allow for multiple injectors in the future. The primary injector used by Proxy is still MetaDataInjector, however it now extends FunctionDataInjector which implements the Injector interface. FunctionDataInjector is now located within the reflect package instead of sample.
