检测golang方法是否是内部方法？

Question

I'm writing a function that iterates over the methods on a given struct and binds the methods to handlers. I would like to skip over internal methods if possible. I'm not sure if this is possible to do so explicitly - I reviewed the documentation for the reflect package and I didn't see a means to detect if a given Value is an internal method. I know I can get the method's name, and then check if it starts with a lowercase character but I'm not sure if there's a kosher way to accomplish this. It's also possible that the internal / public boundary really only exists at compile time anyways, so there really isn't even a way of knowing this beyond the method's name. In either case I'd like to know for sure. Thanks!

The reflect package will not give you unexported methods via Type.Method. Pretty much, if you can see it via reflect, it is already exported.
