Sorry about that. 

Is there anything you can think to do so that we can do to make this a compile time error in the future? Somehow statically asserting that vmEntryCustomGetter/vmEntryCustomSetter match GetValueFuncWithPtr/PutValueFuncWithPtr?

That sounds good! I'll add `static_assert` which checks # of parameter matches with PutValueFuncWithPtr etc. as a first step :)
