 - All operations become statically analyzable, reducing to constants.
 - `assert()` calls get eliminated when conditions are provably true.
 
-It's fundamentally impossible for heap allocation to work with compile-time evaluation, and this applies to C, Zig, and Rust equally.
+This optimization requires stack-allocated buffers with constant addresses. Heap allocation breaks the optimization because the compiler can't trace memory operations through dynamic allocations.
 
 [Link-time optimization](https://en.wikipedia.org/wiki/Interprocedural_optimization) with `-flto` should allow GCC and Clang to perform these optimizations even when the code is split across several object files.
