You will find that debug.getinfo() does have the source used to create the chunk when you use loadstring()
> loadstring[[function foo() print("Hello World!"); end; function bar() end]]() print(debug.getinfo(foo).source)
function foo() print("Hello World!"); end; function bar() end
However this isn't quite what you asked for. It may be a usable workaround, though. If not, I don't think that it should be incredibly difficult to add in (though it seems too expensive to me for something that would be provided in Vanilla Lua)
