You can use stand-alone exportation to add new exports and the like in 
files that add bits, but package dependencies and nicknames should 
probably be relatively statically definable (and accrue monotonically 
unless you're ripping stuff out).

Packages, imho, are there to control some of the raging fury that is a 
rapid-prototyping language. If you don't know yet what depends on what 
module-wise, then you should expect your package definitions to be 
revisited from time to time.

Possibly you could post the problem (if there is one) that the 
inability to extend a package object dynamically is causing you?
