Well, if you really want to know, I'm doing low level rapid development 
involving lots of memory manipulation. I don't have time to tweak 
userdata and then wait tens of minutes for the project to rebuild.

As such I've plugged malloc and free into Lua, along with the 
equivalents of peek and poke, in order to do the low level memory 
manipulation. I implement my interfaces in Lua using these primitives, 
meaning all I have to do to update the system is save the file.

One day, when the system is stable and fully featured, I might rewrite 
the interfaces to use userdata, but not any time soon.
