Hi t, Yes, I know that Lua support OOP, with several implementations and using metatables. I have not looked in detail. But the idea of shared similarities while being at opposite extremes of the programming spectrum/experience is more related with both sharing minimalist concepts applied everywhere (objects and messages for Pharo, tables and functions for Lua), but one provided a full IDE/GUI and being tied with a programming paradigm, which makes it great for agile prototyping, while the other offers just the bare minimum and you arm your puzzle from there regarding tools, paradigms, which makes it great for embedding.
