Re: [Proposal] _GETNAME upvalue

[Marcus Mason <m4gicks@...>]

You can already produce this effect in lua. This is not a complete recreation because real extension methods (a la C#) should override methods no matter where they come from. Lua doesn't have methods so it doesn't make sense.

Personally this seems a bit pointless because you can just use __index on a proxy table to achieve this effect since there's no methods and symbol resolution in lua.

I personally don't see the use of it.

local _GETNAME = function(o, k)
  if type(o) == "table" and k == "insert" then return table.insert end
  return o[k]
end

This allows doing t:insert(foo) on any table t.
