Totally. setfenv and getfenv are important 'back room boys' in Lua
5.1. Once you get the concept, they suddenly open up a universe of
possibilities.

So, I don't quite understand why easily accessing the function
environment has become an outdated/deprecated concept.

As for 'in module(...) do', yes the syntax makes sense. But years of
programming language design practice are against it.  The idea of
separate 'compilation units' occupying their own namespace is well
established, e.g. 'package' in Java.
