Hello all,

Is there a straightforward way to indicate that two modules should not be used 
together in the same program?  Preferably one that does not require editing
both 
of the modules?

The application I have in mind is when one is making available an experimental 
module which is planned to replace one that already exists; it's useful for the 
experimental module to be able to say, "Hey, use me _or_ the standard module, 
but not both of us."

Any thoughts ... ?

Thanks & best wishes,

Only at run-time (because of separate compilation) - you can 
iterate ModuleInfo and assert that only one of modules is 
available.
