Please give a concrete use case. As per your direction, the travel agent

I think that this is _always_ a mistake to expose the implementation of 
functions to customers as part of the interface. I had thought that 
there was a unanimous consensus on this issue in the software world.

Nevertheless, if you wish to expose your implementation, you can do it 
with a simple hyperlink from the public interface to your code or 
business process specification.
