You typically wouldn't replace a function with a no-op since changing who allocs/frees memory is almost certainly an API change which I never claimed my solution would support. The thing my solution would be useful for is for fixing small errors that are tedious to go through a whole compile cycle for. It would be a replacement for modifying values directly in the debugger to try and fix issues (to see if the fix works) and not turn C++ into LISP.
