I would just use C++ standard function `at()' (e.g. as found in vector<T>)

Sure. For regular functions, using default-valued arguments would be
fine. But I think the mechanism would be much more transparent if the
compiler did the heavy lifting.
1- Add a class/function attribute that makes the compiler add 3 hidden
args for the caller location.
2- During code generation, the compiler fills in these values at call
sites.
3- The callee accesses these values by referencing specially named
arguments (much like 'this') or via __builtin_* accessors.
I think I prefer using __builtin_*.
