Ok that is half my idea. Let it sort out at link stage. But that does not cover like libc and dynamic dependencies.

The advantage of being able to generate list of solvable with what is needed to solve allowed smallest and fastest code possible.

Just like now gcc can solve maths functions. Solvable storage of some form allows same kind of solve functions to be done with all libs on the system.

Yes I never found that page.
