After all, in a typical C program there's a ratio somewhere around 10 : 1 of stack objects allocated : objects allocated on the heap (malloc, strdup). Yet stack object allocation is almost never checked for failures. So you're making your code considerably longer and harder to understand in order to catch failures in only 1 in 10 memory allocations.
