Awkward?  How?

Why would this be more configurable?  You could achieve the same thing by 
binding a private method to the native code and wrapping that.  In 
addition, you wouldn't need to add a whole other hashtable, and it would 
be much more transparent to move the implementation of a method back and 
forth between native and p-code.
