It's "Lua".

This is irrelevant. The Lua API is a C library like any other.

Feel free to imagine that the example is one of a class mapping 
to data in a database, and the equality test includes accessing 
the database.

No, I don't have to do this, your assertion is baseless. The LuaD 
library is fairly complete (though there's still a lot of room 
for higher-level features), and the example posted works fine and 
will work fine for the time being because the aggregate is a 
struct, not a class, and will remain so. I don't have to subvert 
the type system in that module at all.
