Hmm, what's the point of single-stepping over a simple data assignment though? And when the initialization involves function calls, the debugger will step into those anyway. One advantage of initialization via compound literals is that you can make the target immutable, and you won't accidentially get any uninitialized junk in unlisted struct members, e.g.: const vec3 vec = { .x = 1.0, .y = 2.0 }; ...vec.z will be default-initialized to zero, and vec doesn't need to be mutable.
