This isn't necessarily a flaw. It's inefficient in Lua, but
there's no performance loss in LuaJIT (*). You may want to
separate these 'code smells' into categories that can be turned on
or off. Or maybe offer different profiles.

(*) The array part of LuaJIT tables is zero-based internally,
    but the visible semantics for {} and # stay the same.
