Interesting idea. Another way of improvement is to use alloca() for small local (to function) objects but there is no direct way to know if a variable is local

Interesting idea. Another way of improvement is to use alloca() for small local (to function) objects but there is no direct way to know if a variable is local or not (in C and C++ at least). > We can, but then convincing the rest of the world to change such a basic building block of C code is quite hard. I can be made with static analysis or binary instrumentation.
