Not to be a nitpicker (and I'm not arguing against what you say in the 
rest of your post), but calling Lua a functional language seems a bit 
too strong to me.

I completely agree that functional features (especially closures) are 
quite a fundamental part of Lua, but so are more imperative features.

Lua code can be written in a pure imperative style, without using 
functional features and heavily relying on side effects, and it doesn't 
seem unnatural or harder.

At the same time, I agree that (with proper conditions, i.e. function 
definitions, and practice) you /can/ write Lua code that looks mostly 
functional and doesn't feel alien.

The fact is, IMO, Lua cannot be framed in either category, since it 
supports both paradigms (with a slight imperative flavour, 
out-of-the-box) with ease. And that is one of its selling point.
