rustc will prevent us from referring it directly, nor can
static FOO: u32 = 0; const REF: &u32 = &FOO; // error const REF2: *const u32 = std::ptr::addr_of!(FOO); // error
No practical use, just for theory.
I believe that technically rustc can do that, but practical it reject to compile I guess because static field value may changed by internal mutability. But what if we only need its address, which will never change? Thanks.
