Re: Most awesome string metatable hack

[Elias Barrionovo <elias.tandel@...>]

Since we're talking 'bout cool metatricks, here's a fun, but mostly useless one:

setmetatable(_G, {__index = function(_, v) return v end})
debug.getmetatable('').__sub = function(s1, s2) return s1..' '..s2 end
print(hello - world)
