This is what I was suspecting. First I wanted to bundle the "loader"
functions in the shared library itself, but finally I realized that
the only really working way is to have a pure shared library
(, and a "loader" Lua script - lqt.lua, which will handle
things like dependencies between modules. This way "require 'lqt'"
would still work as I imagined.

Thanks everyone for the pointers. I will first try to externalize dependencies in Lua (like move msgpack encoding from inside zeromq socket to Lua wrapper) but if this does not work for some libraries, I will probably end up doing the same as Michal.

Michal, please let us know if you implement this chained loading and how you solve it.
