How complete is the Lua engine?

[falseprophet]

I haven't played MTA since around 2006 or so. When there was only race mode. The scripting engine back then lacked... several things. I am curious as to how complete the Lua engine itself is. I have looked at the MTA function documentation on the wiki and it's very impressive right now. But I am curious of the Lua engine.

For example, can we load libraries? Such as a DLL written in C?

You can have server side modules that are written in C, this isn't possible client-side. Unless you want to add a way to access another system (e.g. IRC, MySQL etc) there's not much reason to use it.
