David Arnold be924bcb27 ref: reduce exposure to callLibs
for clarity's sake, expose which function uses final and prev, so that
people can have a clearer understanding how they relate to each other
in terms of dependencies.

also a simple `{ lib = final; }` probably does not warrant a complete
callLibs obscurization.
