> Are there features in Lua that could be removed to create a simpler language?
Of course there are. It has been done, too. Many times.
One such language is Lua 1.0 — I have it on my machine.
Features that it does not have:
1. An interactive interpreter.
$ lua1.0
usage: lua filename [functionnames]
2. Documentation
"There is no documentation, except the test programs. The manual for Lua 1.1
probably works for this version as well."
There is an 11-page research paper [1] called "The design and implementation
of a language for extending applications". It is worth reading even now.
