LÖVE

Many thanks for the help bartbes, I would have never figured out declaring the arg locally, since it works in 0.7.2 without doing so.

High detail map generation time (loop performance):
11.4 secs -> 5.6 secs

Frames per second in battle (pure rendering):
204 FPS -> 255 FPS

No side effects noted, color me impressed.

I'll note that that was only how to get an equivalent table, oftentimes you can get by without turning it into a table.
Also, that's not 0.7.2, that's lua 5.1(.4), luajit, as a re-implementation decided never to add this deprecated feature in the first place.

I updated the links in my original post for LuaJIT 2.0.0-beta8.

Will LöveJIT be a part of official LÖVE builds in the future?

At the moment, LuaJIT is beta software. So no "official" LÖVE builds will use LuaJIT for the time being.

That's disappointing, the LuaJIT beta is more stable than many other software projects marked as "stable".

LuaJIT 1.x is not in beta, but it isn't as fast as LuaJIT 2 and it doesn't have the FFI. There would still be substantial improvements over regular Lua though.

It's not just about stability, what about things like availability?

LuaJIT has ARM support as well as support for nearly every desktop architecture besides OSX PPC, which should be phased out anyway.

Not that availability.

Then what? Are we forced to use the software dependency systems in Linux distributions? Because that's terrible design by them if we are.
