Too complicated for what? The only case I can think of would be if some tool were blindly trying to re-use the same code for Arev1 and Arev2, or if some tool failed to account for the possibility that the same identifier might show up in different modules. These are just two ways of describing the same kind of broken-ness, and are easily handled by scoping (whether in one's symbol table management or the way one generates labels for use in code). > But you talk about behavioural changes.

Thus you don't > have to rev B just b/c A is updated. If an update to a module can't change behaviour (where behaviour includes signatures / interface definitions), then why does it matter?
