I'd suggest you generate that BIF/function when you are building your big module.

You mean hashing after normalizing line numbers (e.g., setting them all to zero)? That worked well for a similar application, when applied to record definitions. (The goal at that time was to transparently permit many clashing record declarations, included from all sorts of places not known at compile-time, to coexist.)

Note that if you are merging modules, this approach _will_ encounter name clashes.
