As the open source author in question, I'd politely ask everyone to not draw overly-generic conclusions from an ancient discussion in some third-party forum, which links to a (now) resolved bug report.

Open source is not a one-way street. By publicly disparaging open source projects, you're actually harming the ecosystem you rely on.

Please accept my apologies. Stable LOVE ships a pretty old version of LuaJIT; I didn't realize it'd been resolved upstream.

LuaJIT was originally made with some x86 assembly wizardry so I'm not surprised to hear that the ARM version is worse.
