One thing I like about connecting to linker artifacts is that it restricts the problem from how to build some module interface to how to build an ABI equivalent interface for a particular binary in a particular ecosystem.

It's still not a trivial problem, but it's one we have some experience in providing solutions for.

Hello,

As discussed in previous meetings, we need to solve the problem on how
to solve the discovery of the metadata for modules. This paper uses
the "linker arguments" idea.

It makes the caveat about "interface-unit-only module libraries" as
well as to the fact that this will eventually be superseded by proper
package management (although I think it will remain useful as a
lowest-common-denominator option even then).

me know what you think.
