The progrmming language Eiffel has a module linking notation used to
direct its compiler.
It recognised that modules get aggregated into packages, that packages
get aggregated into larger packages and so forth.
Each level of this hierarchy can get name clashes. So this notation
has a mechanism to rename anything on import or export
The idea is that each complete program comes with such a file telling
the compiler in what hierarchy all these modules are to be combined and
be renamed and have their imports and exports renamed.
Presumably such a file can contain information where these modules and
such can be found.
Presumably it can also be wrapped with instructions about finding these
modules, perhaps even rewriting the URLs or module names.
I found this notation described near the end of one of the books
describing Eiffel. I no longer have access to this book, or I'd give yo
a detailed reference.
But I suspect this mechanism shouls be considered when making similar
decisions about Scheme.
