It's ambiguous. There can be (and are) eggs that export procedures of the same 

Dependencies shouldn't get out of sync, and updated versions may change what is 
exported... so I would question exactly what you are doing that would require 
such functionality and whether there would be a better development methodology 
that wouldn't shift the burden from paying attention to what one is using to a 
psychic programme that does what you mean (not what you tell it).
