It was inspired by that post, but not in response to it. Over the 3 or 4 months that I took writing lowkPRO, one of the features I'm most proud of is this, the ability for it to create C callbacks on the fly that just call Lua callbacks and return the value to C. And I would argue that it's not hacky but just well-engineered. After all, everything compiles to assembly at the end of the day, right?
